Return failure/unsupported in RenderDeviceDriverIface::StartDIBits()

Currently, StartDIBits() returns false to mean failure, but failure can
either be "something went wrong" or "operation not supported". Change
the bool return value to a Result enum to tell these two cases apart.
Then change CPDF_ImageRenderer::StartDIBBase() to return when something
goes wrong, and only use the fallback code in the not supported case.
