crrev.com/c/2234684 introduces a new buffer usage flag for hardware VEA
(SCANOUT_VEA_READ_CAMERA_AND_CPU_READ_WRITE). On Kukui this changes
buffer layout, and the camera driver failed to capture correct content
into the buffer in the RAW->YUV reprocessing case.

Since the reprocessing YUV buffer is not used for video encoding, this
CL changes the buffer usage for that use case back to the original
(SCANOUT_CAMERA_READ_WRITE).

This CL also cleans up places that hard-code buffer usage, or makes it
verbose when it has to do so.

Bug: 1105154
Test: capture_unittests
Test: CCA preview, video recording, take normal/Portrait photo (with #zero-copy-video-capture flag on and off)
