Manuel Castilla 153b45037f Compositor: Full frame matte nodes
Adds full frame implementation to Channel Key, Chroma Key, Color Key,
Color Spill, Cryptomatte, Difference Key, Distance Key, Keying,
Keying Screen and Luminance Key nodes. The other nodes
in "Matte" sub-menu are submitted separately.

No functional changes.

Part of T88150.
