These changes fix the Heap-buffer-overflow in Codec__decodeXAACStream runtime error
caused due to unsupported frame length type configuration for LATM streams.
Bug: ossFuzz:67767
Test: poc in bug
Significance:
========
[x] Aligned buffer access for scratch memory and scratch memory optimization.
Testing:
=====
[x] MSVS Conformance and CTS are passing.
[x] All previous fuzzer crashes are tested. No crash observed.
[x] For platforms, Conformance tested with different combinations.
[x] Tested Conformance with gcc builds for x86, x86_64, armv7 and armv8.
[x] Tested Conformance with clang builds with address and memory sanitizer flags for x86_64 and armv8.
There hasn't been a non-neon platform build in years. Even the NDK hasn't supported non-neon for two years now.

reported by disabling some code checks which are related to EC.
Bug: ossFuzz:62003
Test: poc in bug
These changes handle the divide-by-zero runtime error
reported when the active lines become zero in
quantization. The issue is reported with AAC and the
same changes are extended to USAC.
Bug: ossFuzz: 62977
Test: poc in bug
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.

* Fix for divide-by-zero in ixheaacd_sbr_env_calc
These changes handle the divide-by-zero runtime error reported
while calculating the energy because the consecutive frequency bands
were coming same.
Bug: ossFuzz:63038
Test: poc in bug
* Fix for divide-by-zero in ixheaacd_calc_stop_band
These changes handle the divide-by-zero runtime error reported
because sampling frequency comes out to be zero.

Test: poc in bug
These changes handle the divide-by-zero runtime
error reported when the average bits become zero
in bit reservoir factor calculation.
Bug: ossFuzz: 62291
Test: poc in bug

while calculating the energy because the start sample and end sample
were coming same.
Bug: ossFuzz:62766
Test: poc in bug
These changes handle the index-out-of-bounds runtime error
reported when the value of residual sampling frequency index
is greater than max residual sampling frequency index.
Bug: ossFuzz:62707
Test: poc in bug
These changes handle the divide-by-zero runtime error
reported while calculating the border vector value because
the value read from bitstream was coming greater the expected value.
Bug: ossFuzz:62633
Test: poc in bug
These changes handle the Divide-by-zero runtime error reported
while calculating the energy estimation because the
consecutive border vectors were coming same.
