fix(trng): avoid undefined behaviour in pack_entropy
When nbits is a multiple of the word size, the pack_entropy function
right shifts the mask by the type width, which is undefined. In
practice, the 64-bit shift compiles to a no-op and the implementation
depends on this behaviour, so this patch changes the function to skip
the masking if nbits is multiple of the word size.

refactor(trng): discarding the used entropy bits
This patch discards all the used entropy bits from the global memory
pool after being delivered to the requester (lower exception levels) by
overwriting them with zeroes.
It effectively implements the requirement, as part of TRNG FW interface
listed at DEN0098 (section 1.2).

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.

Add TRNG Firmware Interface service
This adds the TRNG Firmware Interface Service to the standard
service dispatcher. This includes a method for dispatching entropy
requests to platforms and includes an entropy pool implementation to
avoid dropping any entropy requested from the platform.
