arm64: introduce separated bits for mm_context_t flags
Currently mm->context.flags field uses thread_info flags which is not the best idea for many reasons. For example, mm_context_t doesn't need most of thread_info flags. And it would be difficult to add new mm-related flag if needed because it may easily interfere with TIF ones. To deal with it, the new MMCF_AARCH32 flag is introduced for mm_context_t->flags, where MMCF prefix stands for mm_context_t flags. Also, mm_context_t flag doesn't require atomicity and ordering of the access, so using set/clear_bit() is replaced with simple masks.
