mm-video: vidc: set stride in gralloc-metadata for adaptive-playback

In Adaptive-playback mode, following resolution change, decoder
continues to decode on larger buffer. But the stride is changed
implicitly. Set the updated stride in gralloc-metadata in each
buffer, so HWC/GPU can read the stride to interpret the buffer's
geometry correctly.
