memory: Access MemoryRegion with endianness
Preparation for collapsing the two byte swaps adjust_endianness and
handle_bswap into the former.
Call memory_region_dispatch_{read|write} with endianness encoded into
the "MemOp op" operand.
This patch does not change any behaviour as
memory_region_dispatch_{read|write} is yet to handle the endianness.
Once it does handle endianness, callers with byte swaps can collapse
them into adjust_endianness.
