Generate PSA constant names in CMake build dir

Browse Source 
This commit modifies the generate_psa_constants.py script to take as
input argument the location of where to write the
psa_constant_names_generated.c file.
For make-based build system, this commit does not change anything.
For CMake build system, this commit modifies the generation location of
that file to be inside the build directory and include it from there in
psa_constant_names.c

Fix #3365
