refactor[allocator]: Refactor allocator flow

1. Allocator api is determined by buffer type.
2. Allocator ctx is determined by both buffer type and buffer flags.
3. All allocator dma_heap / drm / ion / ext_dma should support different
buffer flags.
4. The buffer flag supports cacheable / 32-bit / contig options.
5. Add flags update flow on allocator create process.
6. Add mpp_dmabuf_has_partial_ops to disable dmabuf partial ops when the
kernel driver has bug.
