Add test cases that verify various bits and pieces of the legacy
devicetree macros match the new APIs.
Writing these test cases without giving rise to deprecated macro
warnings which might break people's CI if they build with -Werror
requires turning off the __WARN() generation in
devicetree_legacy_unfixed.h. The entire file is deprecated at this
point and must be explicitly enabled with an opt-in Kconfig option, so
there isn't any harm in doing this.
Nevertheless, take a minimally invasive approach to avoiding __WARN()
generation in gen_legacy_defines.py, to avoid the possibility of
breakage. This code is basically frozen anyway, so hacks like this
won't cause maintainability problems since it isn't being actively
maintained.
Use the new tests as fodder for a migration guide from the old API in
the documentation.
