* 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

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.

Check configuration data obtained after audio Pre-Roll
parsing against current configuration. Update only when
configurations are different.

For erroneous stream, coupling channel initialization memory
was overlapping with SBR scratch memory usage, causing unwanted
reset of the some of the pointers.
All initialization should take place in persistent memory.
As a fix, replaced scratch with persistent memory for initialization.

We found that error return was not being handled properly
in ixheaacd_applysbr() function. This led to a wrong value
being propagated which led to a stack buffer overflow.
Also, a flag for checking if any previous frames encountered
a fatal error has been added to ensure that further processing
of frames doesn't happen after encountering a fatal error.

In ixheaacd_dec_main(),ixheaacd_config() returned from ixheaacd_read_bit_buf()
due to setjmp/longjmp changes which resulted in ixheeacd_decode_create() not
being called which is needed to initialize many pointers which in turn resulted in
Segementation fault.
As a fix, added a flag decode_create_done which will tell the status of
ixheeacd_decode_create() func and ixheaacd_usac_process will be called
based on this flag.
