libhwc2.1: Add uncompressed YUV format to candidate of m2m output

SBWC format has dst crop alignment restriction so
SBWC format could not be supported by m2mMPP in some dst size.
This patch adds additional uncompressed YUV format to
candidate list for m2m ouput to cover this case.
SBWC format would be used only if there is m2mMPP
that can support dst crop size
and uncompressed YUV format would be used if
there is no m2mMPP that can support dst crop size.
