Add MediaTek private format for reprocessing

Add MediaTek private format for reprocessing

In this CL, we add DRM_FORMAT_MTISP_SXYZW10, a 10-bit private bayer
format for private reprocessing on MediaTek ISP P1. We change the logic
around resolving the DRM format for IMPLEMENTATION_DEFINED buffers. When
CAMERA_READ usage flag is present, we consider it to be a buffer for
reprocessing and resolve the format to our private format.

BUG=b:130851309
TEST=Emerge and deploy minigbm cros-camera-libcbm cros-camera
cros-camera-hal-mtk, then verify that ZSL is working.
