media: VideoFrame has ReadOnlySharedMemoryRegion

VideoFrame uses a buffer produced by a decoder and a buffer input to
an encoder. The buffer of VideoFrame is not written by the source
producer in both cases. VideoFrame has UnsafeSharedMemoryRegion when
its storage type is STORAGE_SHMEM. This CL changes VideoFrame to
have ReadOnlySharedMemoryRegion to match today's use scenarios.
