esp_hw_support: Remove compare_set.h API

This function removes the following legacy atomic CAS functions:

From compare_set.h (file removed):
- compare_and_set_native()
- compare_and_set_extram()

From portmacro.h
- uxPortCompareSet()
- uxPortCompareSetExtram()

Users should call esp_cpu_compare_and_set() instead as this function hides the details
of atomic CAS on internal and external RAM addresses.

Due to the removal of compare_set.h, some missing header includes are also fixed in this commit.
