Carlos ValdesandJonathan Bennett 204f88ddfe fix(nrf54l15): restore the nrf54l15dk build (#11410 )

* fix(nrf54l15): restore the nrf54l15dk build

Three unrelated faults stacked up, so the env has not built from a clean
cache for some time. All three were diagnosed in July but never committed.

Pin framework-zephyr to 3.40201.251021 (Zephyr 4.2.1). Seeed's platform
script only maps their own seeed-xiao-* board ids to a package; any other
board -- ours included -- falls back to whatever platform.json declares as
the default, which is now Zephyr 4.4.0. Its west manifest pulls a CMSIS_6
whose cmsis_gcc.h calls the ACLE builtins __sxtb16/__sxtab16, and none of
the GCC ARM toolchains PlatformIO ships (8.2.1/9.2.1/9.3.1) declare them in
arm_acle.h. In C that is only an implicit-declaration warning; in C++ it is
a hard error. So a fresh cache silently breaks the build even though
nothing in the tree changed.

Guard the MMC5983MA case in MagnetometerThread with __has_include. The
switch arm constructs MMC5983MASensor unconditionally, so any env whose
libdeps lack SparkFun_MMC5983MA_Arduino_Library fails with "expected
type-specifier before 'MMC5983MASensor'".

Add Print::availableForWrite() to the nrf54l15 Arduino shim. The shim
declares flush() but not availableForWrite(), which StreamFrameWriter
calls -- so it went unnoticed until that code landed.

Verified: clean build of nrf54l15dk from an empty package cache, SUCCESS in
16:01, FLASH 39.04% (570804 B of 1428 KB), RAM 65.65%. The three had never
been exercised together -- a previous run with only the pin applied got
17:30 in before hitting the other two.

* review: collapse the pin rationale to one repo-local comment

The block was pasted twice, and both copies pointed at a note that does not
exist in this repository. Kept one, and only the part a reader here can act
on: why the fallback happens, and why it is a C++ error rather than the
warning the pure-C Zephyr core gets away with.
