Rather than defining values that should appear in limits.h in posix_features.h, move them to a separate file.
Undefine any externally defined POSIX limits, since Zephyr would prefer to define those based on Kconfig values.
Additionally, convert runtime invariant values to constant if they should be constant.
Fixes #80409
Testing done
Note
Running
clang-format
does not produce code that passes compliance checks due to strangeness withCOND_CODE_1()
, so some lines are manually formatted (as they had been inposix_features.h
).
