Strengthen dataspace guarantees in SurfaceFlinger.
Correctly converting from yuv to rgb in RenderEngine requires that the
buffer dataspace is accurate. So, if the dataspace on a layer differs
from the buffer then update the dataspace in the buffer's metadata to be
consistent.
Moreover, some GPU drivers do not perform yuv2rgb in a reasonable way
when the dataspace is UNKNOWN. In that case, reauthor the dataspace to
be sRGB so that there is consistent behavior for an UNKNOWN dataspace.
Finally, some GPU drivers cache gralloc metadata on creation of GPU
resources, which is not compliant with gralloc expectations. So that
vendors have some time to fix the drivers and so that GSI tests pass,
recreate GPU resources when the vendor partition is old and the buffer
is a YCbCr format.
