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.
Bug: 33073518
Test: Tested with -fsanitize=alignment enabled on avcdec
Change-Id: I470bc868dde7049be12bee06ee0ba0c4c4bd8566
