* Loudness leveling support for encoder and decoder
- Addition of loudness leveling support to encoder and
decoder as per ISO/IEC 23003-4:2020/Amd.2:2023(E)
Testing:
Encoder: Smoke-test
Decoder: CTS and Conformance for x86, x86_64, armv7 and armv8 are
passing
* Addressed review comments
* Addressed minor nits in documentation

These changes handle the index-out-of-bounds runtime error
reported when the bit consumption exceeds the bit reservoir
and global gain reaches the maximum value. The issue is
reported with USAC and the same changes are extended to AAC.

Test: poc in bug
These changes handle the Divide-by-zero runtime error reported
when the drc gain coordinates are identical or slope is
perpendicular to the gain value.
Bug: ossFuzz:61683
Test: poc in bug
These changes handle the runtime error reported when the gain
value exceeds the maximum supported value because of zero
spectrum. This is resolved by exiting the rate distortion loop
when zero spectrum is detected. The issue is reported with AAC
and the same changes are extended to USAC.
