linuxkpi: Split <linux/compiler.h>

[dumbbell]

Summary

On Linux, they split the content into three headers:

1. <linux/compiler.h>
2. <linux/compiler_types.h>
3. <linux/compiler_attributes.h>

The first includes the second, which includes the third.

<linux/compiler_types.h> is also included on the compiler command line by default! I added that to the compilation flags of the DRM drivers.

This allowed me to drop at least one:

#ifdef __FreeBSD
#include <linux/compiler.h>
#endif

Note that our copy of <linux/compiler.h> contains definitions which are not defined by Linux' <linux/compiler.h>. I left them alone.

This is part of the update of DRM drivers to Linux 6.10.

What is the reason not to include them as <linux/compiler_types.h> here and in the other file if that is an official Linux[KPI] include file?

Mmm, probably should be
