19609: drivers/lpsxxx: avoid float arithmetics r=aabadie a=maribu
### Contribution description
Perform computation directly in centi-degree-celsius to avoid floating point arithmetics. In addition, use scientific rounding in the division.

19599: examples/wasm/wasm_sample: revert prebuild WASM r=kfessel a=maribu
### Contribution description
Running `make` in the wasm example modifies the `hello_prebuild.wasm` example, making it easy to sneak in unwanted changes. This reverts such an instance and modifies the Makefile to only recreate/update `hello_prebuild.wasm` with:
make hello_prebuild.wasm

19600: build-system: Allow out of tree BUILD_DIR r=maribu a=maribu
### Contribution description
- Replace all users of `$(RIOTBASE)/build` with the already present `$(BUILD_DIR)` variable
- Replace all users of `$(BUILD_DIR)/pkg` with the already present `$(PKGDIRBASE)` variable
- Create a `CACHEDIR.TAG` file in the `$(BUILD_DIR)`

19593: boards/msb-430: add documentation r=maribu a=maribu
### Contribution description
This adds basic documentation, schematics, pinouts, and info how to get started with the `msb-430` board.
19597: sys/shell: Add coreclk command to shell_cmd_sys r=maribu a=maribu
### Contribution description
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.

19558: boards: support for Olimex MSP430-H1611 board r=maribu a=maribu
### Contribution description
- implement a clock driver so that boards declare their clock configuration, rather than initializing the CPU clock in `board_init()` by hand
- Note: A board can still overwrite the weak symbol `clock_init()` in case some really crazy things should happen
- add support for the Olimex-H1611 board
19598: dist/tools/insufficient_memory: fix collection of app folders r=maribu a=maribu
### Contribution description
There is actually a make target to list the applications in the repo. Let's just use that.

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.
Provide a common clock initialization driver rather than leaving
clock initialization to the boards code. A declarative description of
the board's clock configuration using a struct does still allow to
fine-tune settings. In addition, a board is still allowed to just
provide a custom `void clock_init(void)` if there really is the need
to do crazy things.
19596: dist/tools/insufficient_memory: handle address space wraps r=aabadie a=maribu
### Contribution description
When a region wraps around the address space, the application typically is way too large to fit into the 16 bit address space of 16 bit or 8 bit platforms.

When a region wraps around the address space, the application typically
is way too large to fit into the 16 bit address space of 16 bit or
8 bit platforms. Hence, classify this as "too big" in the tools.
19594: sys: drop broken and legacy Mac OS handling r=maribu a=maribu
### Contribution description
This drops special handling for Mac OS (X) `native`, which is not supported anymore anyway and causing issues when building for non-`native` targets on Mac OS.

18056: pkg/cmsis: use unique package for CMSIS headers, DSP and NN modules r=benpicco a=aabadie
19571: cpu/stm32/periph_adc: fixes and improvements for L4 support r=benpicco a=gschorcht
### Contribution description
This PR provides the following fixes and improvements for the `periph_adc` implementation for STM32L4.
- Support STM32L496AG added.
- Instead of defining the number of ADC devices for each MCU model, the number of ADC devices is determined from ADCx definitions in CMSIS header.
- MCU specific register/value defines are valid for all L4 MCUs, model based conditional compilation is removed.
- The ADC clock disable function is fixed using a counter. The counter is incremented in `prep` and decremented in `done`. The ADC clock is disabled if the counter becomes 0.
- For boards that have not connected the V_REF+ pin to an external reference voltage, the VREFBUF peripheral can be used as V_REF+ (if supported) by setting `VREFBUF_ENABLE=1`.
- The ASCR register is available and has to be set for all STM32L471xx, STM32L475xx, STM32L476xx, STM32L485xx and STM32L486xx MCUs. Instead of using the CPU model for conditional compilation, the CPU line is used to support all MCU of that lines.
- Setting of SQR1 is fixed. Setting the SQR1 did only work before because the `ADC_SRQ_L` is set to 0 for a sequence length of 1.
- Setting the `ADC_CCR_CKMODE` did only work for the reset state. It is now cleared before it is set. Instead of using the `ADC_CCR_CKMODE_x` bits to set the mode, the mode defines are used.
- Support for V_REFINT as ADC channel added.
