refactor(trng): cleanup the existing TRNG support
This patch adds the following changes to complete the existing
TRNG implementation:
1. Adds a feature specific scope for buildlog generation.
2. Updates the docs on the build flag "TRNG_SUPPORT" and its values.
3. Makefile update and improves the existing comments at few sections
for better understanding of the underlying logic.
