rGad528a6b174e: linuxkpi: Define diagnostic macros like `might_resched()` or `cant_sleep()`

Summary

They are no-ops on FreeBSD.

While here, move the already defined might_sleep*() macros from <linux/wait.h> to <linux/kernel.h> where they belong.

The DRM generic code started to use might_fault() in Linux 6.12.

This is part of the update of DRM drivers to Linux 6.12.
