Decoder: Remove unnecssary optimization while setting MV context
...
Few MV cabac contexts were being used as WORD16 pointers
but were not guaranteed to be aligned to 2 byte boundary.

Decoder: Reset p_curr_ctxt->i1_ref_idx using memset
...
Since p_curr_ctxt->i1_ref_idx is not guaranteed to be 4 byte aligned,
use memset instead of using it as an int pointer.
On platforms that do not support unaligned stores, this change is needed

Decoder: Aligned pi1_left_pred_mode[8] in _DecStruct definition
...
This array is sometimes accessed as two WORD32 variables.
On platforms that do not support unaligned load/stores, this needs
to be aligned to 4 byte boundary.

Decoder: Ignore dangling fields during flush
...
If decoder has decoded one field and is waiting for next field,
and flush is called, then ignore the current decoded field.
This is needed to ensure seek works in case of flush between field
decode calls
Bug: 32391809
Test: Tested manually by decoding clip in the above bug in Photos app

Initialize video_format to 5 and colour_primaries, transfer_characteristics
and matrix_coefficients to 2 to signal that these are not present in the bitstream.

from reference lists. This is needed to decode streams where few pictures
are missing.
