Cleanup: _F_types_h should be _F_type_h and some macros have misplaces the "s".

Cleanup: _F_types_h should be _F_type_h and some macros have misplaces the "s".

The f_type project is singular, so do not use an "s" in the name.

Some of the macros in the type_array.h file were not converted from having the "s" after the _t to more accurately matching the type name.
For example uint8s_t should have macros using uint8s_t instead of uint8_ts.
