Update Zephyr to 4.4.2.
This supersedes #133.

Using Zephyr 4.4 allows to test the CONFIG_USE_SWITCH KConfig option that may (or may not) improve the context switch performances.

As for #133, this update was not checked further than compiling the empty main file.
Please report here any issues with this update.
