SurfaceFlinger: captureScreen buffer set GRALLOC_USAGE_HW_COMPOSER usage
CaptureScreen buffer should set GRALLOC_USAGE_HW_COMPOSER usage, as this buffer
will be composited as one layer by composer at the short time when do screenshot.
Some platforms will check GRALLOC_USAGE_HW_COMPOSER usage and guarantee buffer
be allocated as physical continuous memory, as some composer hardware such as DPU
2D can't handle no-continuous memory without MMU. Without GRALLOC_USAGE_HW_COMPOSER
usage, these platforms will meet problem.
