win32u: Allow selecting 32-bit DDBs into display compatible DCs.
Device context bit depths other than 32-bit are emulated and the real bit depth for display DCs is still 32-bit. Thus, a 32-bit DDB should be allowed to be selected into a display compatible DC even if the DC reports a different bit depth.
Fix a regression from d171d11.
