19735: nrf5x_common: Clear I2C periph shorts r=benpicco a=bergzand
### Contribution description
The I2C peripheral's shortcuts are used with the read and write register to automatically stop the I2C transaction or to continue with the next stage.
With simple I2C read and write bytes these shorts are not used, but are also not cleared by the function in all cases, causing it to use the shortcut configuration set by a previous function call. This patch ensures that the shorts are always set by the read and write functions
### Testing procedure
Should be possible to spot with a logic analyzer and the I2C periph test. Maybe the HIL test can also detect it :)

The `--param=min-pagesize=0` needed since GCC 12 is still needed with
GCC 13. This time at least the message is more meaningful:
note: source object is likely at address zero
This is something that is not expected in a userspace app, but with
bare metal MCUs and often flash or memory mapped I/O starting from
address zero, this warning prevents legitimate code from compiling.
19556: tools/mspdebug: fix `make debug` and `make debugserver` r=aabadie a=maribu
### Contribution description
The semantics of `make debug` and `make debugserver` have changed in the years since the MSP430 integration. This brings the implementation back into line with the current semantics
- `make debug` now starts both mspdebug and GDB, no need to run `make debugserver` prior to `make debug` anymore
- `make debug` no longer flashes the target to not waste flash erase cycles
- GDB mutliarch support is added
- support for selecting a debug adapter by its serial is added

The coreclk shell command now prints the CPU frequency in Hz, which
can be useful for boards with RC generated CPU frequency (e.g.
RP2040, FE310, or MPS430Fx1xx MCUs allow this) which may quite a bit
off the target frequency.

19574: cpu/stm32/periph_gpio: reset PU/PD for ADC channels r=maribu a=gschorcht
### Contribution description
This PR provides a small fix that is relevant when a GPIO has been used as input/output with a pull resistor before it is initialized as an ADC channel.
The PU/PD configuration has to be `0b00` for analog outputs which is corresponds to the reset state. However, if the GPIO is not in the reset state but was used digital input/output with any pull resistor, the PU/PD configuration has also to be reset to use it as ADC channel.
### Testing procedure
- Green CI
- The `periph_adc` test application should still work for any board that supports the `periph_adc` feature.

GCC 12 gives out of bounds warnings when the resulting address is out
of bounds of what GCC assumes to be the valid address space. It seems
that by default the address 0x0 is not considered valid (which would
be a NULL pointer and typically not mapped in a userspace behind an MMU
scenario), but in fact is valid on bare metal hardware. At least on
AVR and MSP430 this needs to be set. On many Cortex M MCUs 0x0 is also
a valid address (e.g. often the flash is mapped there), but seemingly
for them `--param=min-pagesize=0` is already the default. In any case,
it won't hurt to set it explicit for them as well.
An `INSERT AFTER` directive no longer can refer to a different linker
script included with `-T path/to/script.ld`. Instead, this adds wrapper
linker scripts that just `INCLUDE` the three individual linker scripts.
This way, the xfa.ld can safely refer back to sections defined in
the vendor linker script.
For some reason, this approach cause the exact issue it fixes for
binutils 2.40 with the binutils in the CI. We stick with the old
linker flags with binutils prior 2.40 to be compatible with both
conflicting behaviors.
The best approach would be to come up with something that works across
different versions of binutils; but no such solution materialized.
There seems to be a consensus to go for a more ELF centric approach
whenever possible. J-Link seems to work fine with ELF files, so let's
avoid the extra step to create a bin file from the ELF file prior to
flashing.
While testing examples/micropython I notice that the default of miniterm.py is actually miniterm.
To simplify user setups, this checks for miniterm.py first then falls back to miniterm.
19374: makefiles/boards/stm32: fix DFU_USB_ID handling r=benpicco a=gschorcht
### Contribution description
This PR fixes the still existing problem that an application can't be flashed to a STM32 board if it uses `riotboot_dfu` with default VID/PID (1209:7d02).
In PR #18964 item 1, the problem was already described that an application can't be flashed on a board that is using `riotboot_dfu`. Using for example
```python
FEATURES_REQUIRED+=riotboot USEMODULE+=usbus_dfu make -C examples/saul BOARD=nucleo-f767zi \
PROGRAMMER=dfu-util all riotboot/flash-slot0
```
always leads to error
```python
/home/gs/src/RIOT-Xtensa-ESP.esp-idf-4.4/makefiles/boards/stm32.inc.mk:28: *** DFU_USB_ID is not set. Stop.
/home/gs/src/RIOT-Xtensa-ESP.esp-idf-4.4/makefiles/boot/riotboot.mk:87: recipe for target 'riotboot/bootloader/binfile' failed
```
even if `DFU_USB_ID` variable is set as described in documentation.
```python
FEATURES_REQUIRED+=riotboot USEMODULE+=usbus_dfu make -C examples/saul BOARD=nucleo-f767zi \
PROGRAMMER=dfu-util DFU_USB_ID=1209:7d02 all riotboot/flash-slot0
```
The reason is that the variable `DFU_USB_ID` isn't exported and the check 8dc8bf3567/makefiles/boards/stm32.inc.mk (L27-L29) sees an empty `DFU_USB_ID` variable here. It prevents to use `dfu-util` event though the following `dfu-util.mk` will generate a default value for this variable from the `USB_VID` and `USB_PID` variables if necessary.
Commit 6a76b94c6e0ae97bc743cc90d0811e691a35869e of PR #18964 tried to fix this problem but wasn't merged for any reason.
To fix this problem, the check is completely removed. If a board such as `weact-f4x1cx` uses a DFU boorloader and requires a certain VID/PID combination, board's makefile is responsible to set `DFU_USB_ID` variable.
### Testing procedure
It is not necessary to use a real boad, checking the compilation process is sufficient.
1. Using default VID/PID as described in documentation:
```python
FEATURES_REQUIRED+=riotboot USEMODULE+=usbus_dfu make -C examples/saul BOARD=nucleo-f767zi \
PROGRAMMER=dfu-util all riotboot/flash-slot0
```
can't be compiled without this PR but calls `dfu-util` correctly with this PR using the default VID/PID:
```python
dfu-util --device 1209:7d02 --alt 0 --download examples/saul/bin/nucleo-f767zi/riotboot_files/slot0.1678440536.bin
```
2. Using a VID/PID as described in documentation:
```python
FEATURES_REQUIRED+=riotboot USEMODULE+=usbus_dfu make -C examples/saul BOARD=nucleo-f767zi \
DFU_USB_ID=1209:affe PROGRAMMER=dfu-util all riotboot/flash-slot0
```
can't be compiled without this PR but calls `dfu-util` correctly with this PR using the default VID/PID:
```python
dfu-util --device 1209:affe --alt 0 --download examples/saul/bin/nucleo-f767zi/riotboot_files/slot0.1678440536.bin
```
3. Compiling a board with DFU bootloader
```python
make -C examples/saul flash BOARD=weact-f411ce
```
should still call dfu-util with correct VID/PID:
```python
dfu-util --device 0483:df11 --alt 0 --download /home/gs/src/RIOT-Xtensa-ESP.esp-idf-4.4/examples/saul/bin/weact-f411ce/saul_example.bin --dfuse-address 0x8000000:leave
```

The variable `DFU_USB_ID` is used by `dfu-util` to specify the device to be flashed. The STM32 make system prevents `dfu-util` from being used as programmer if this variable is not set, although `dfu-util.mk` generates a default value for this variable from the `USB_VID` and `USB_PID` variables if necessary. Therefore, checking the `DFU_USB_ID` variable is removed here. If a board requires a specific combination of VID/PID for `dfu_util`, it is responsible for setting the `DFU_USB_ID` variable.
Whenever the module of a peripheral driver, i.e., periph_* should be used, the corresponding entry in the
FEATURES_REQUIRED should be added. Conflicts between these modules are
only checked when this entry is present.
