Codec initialization is done with AOT 2 (AAC-LC profile),
but AOT changes abruptly to 42 (USAC profile) in execution
leading to access of uninitialized tables. Hence Added a
check for mismatch in AOT during initialization and
AOT during execution.

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.

When ixheaacd_drc_offset comes negative, we read
backward in bitbuffer. There was no bound check to
make sure it did not go beyond the start of bitbuffer.
This caused a SEGV.

(cherry picked from commit 566b69f066)
Index k is incremented and used as an index of
selection_candidate_info_step_2 array. k can be
max (str_drc_instruction_str->dwnmix_id_count *
selection_candidate_step_2_count), this can be
more than max size of selection_candidate_info_step_2
array.
Hence added a check before assignment as fix.

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.
