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.
Added changes to remove redundant computation
loops in ixheaacd_mps_synt_calc,mps hybrid
analysis & synthesis functions based on number
of non-zero qmf bands.
AAC Core coder changes to take the output samples as 32 bit
and subject to peak limiter to avoid any clipping , at the
same time maintaining precision.

ptr_sbr_qmf->filter_states memory is initialized based on
down_sample_flag. But it's used irrespective of
down_sample_flag values for few testcases.
Therefore assigned maximum memory to
ptr_sbr_qmf->filter_states as a fix in the current CL.

pstr_dec_data->str_usac_data.pstr_esbr_dec is
initialised only when sbr_ratio_idx > 0. We use
this structure when stereo_config_index > 0,
without checking sbr_ratio_idx > 0. Hence a check
has been added as a fix.

In xaacdec even though lpd decoder handle is defined to support 6
channels, only 2 channels are initialized with data (because we
support only stereo in USAC profile). The input stream used for
this issue has 3 channels. When third channel is getting processed
valgrind is reporting un-initialized data usage.
To solve the issue, a conditional check is added based on number
of channels in the bit stream

The maximum number of channels supported for usac profile in
libxaac decoder is two only.Input streams of the below reported
issues contain multi channel,because of multi channel the write
offset is incremented by greater 2, which causes out of bound
memory access while writing.
