vtenc: Disable ARGB/RGBA64 caps on M1 Pro/Max with macOS <13

Browse source 
Fixes #1358.
Passing ARGB64/RGBA64 to vtenc caused the encoding to fail
when running on M1 Pro/Max variants with macOS 12.x, so let's
remove these formats from caps when such scenario is detected.
This issue appears to have been fixed OS-side in macOS 13.0.
