Since fmt no longer has a significant advantage in stack consumption,
we need to bump the `MIN_SIZE` guard that prevents causing stack
overflows due to the printing of the stack consumption.
Hooking into the existing wrappers for `malloc()`, `calloc()`,
`realloc()`, and `free()`, the new (pseudo) module `malloc_tracing`
prints out the calls to the given functions, the program counter of
the caller, as well as the return result.
The intent is to aid debugging double-frees, invalid frees, or memory
leaks.
The commit 98478e02fe removed the setting of the CFG_TUD_MAX_SPEED define to OPT_MODE_DEFAULT_SPEED. This setting is usually not required since CFG_TUD_MAX_SPEED is determined from CFG_TUSB_RHPORT{0,1}_MODE. However, this does not work for STM32F429I-DISC1 where the HS port is used via the internal FS-PHY. Therefore the default speed setting is added again.
With PR #18835, the automatic generation of descriptors for the most common device classes and their handling was introduced. The update of the documentation was forgotten.
It turns out that the fix for the missing terminating newline is not
robust. This hopefully fixes the issue and resolves the following
error message:

Modern binutils complain about segments with RWX permissions. While
this is indeed a bad habit, RIOT ignores segments permissions anyway.
(We do have a `mpu_noexec_ram` module to disable execution of all of
RAM, which would do so regardless of the segment permission.) So for
now, we can safely just disable the warning.
This fixes:

The test (at least locally) fails on the long shell line detection in
`master`, as the EDBG UART adapter drops chars when more than 64 bytes
are send at a time. This works around the issue:
- The line buffer in the test is reduced to 60 bytes, so that
overflowing it becomes possible with sending less than 64 bytes.
- The test script is adapted to exceed the shell buffer size by one
byte only (due to linefeed char), rather than significantly.
- Sending more than 64 bytes would result in the linefeed being
dropped by the EDBG adapter and the test failing
Finally, the shell buffer is no longer allocated on the stack and,
hence, the main stack size could be reduced a bit. The test still
passes on the Nucleo-F767ZI which is notorious in failing on tight
stacks due to the MPU stack guard - so the stack size reduction is
expected to work for all boards.
This fixes compilation with GCC >= 12.x, which is unhappy about the use
after free:

It turned out that 4983f8bb60 was not
enough to allow the tool to be executed from within
`dist/tools/backport_pr`. With this, I successfully tested it :)
