chore: simplify the macro names in ENABLE_FEAT mechanism 

Currently, the macros used to denote feature implementation
in hardware follow a random pattern with a few macros having
suffix as SUPPORTED and a few using the suffix IMPLEMENTED.
This patch aligns the macro names uniformly using the suffix
IMPLEMENTED across all the features and removes unused macros
pertaining to the Enable feat mechanism.

FEAT_SUPPORTED --> FEAT_IMPLEMENTED
FEAT_NOT_SUPPORTED --> FEAT_NOT_IMPLEMENTED
