[OpenJDK 2D-Dev] RFR: 8264475: CopyArea ignores clip state in metal rendering pipeline

[Jayathirth D V]

In MTLBlitLoops.copyArea() we use standalone encoder which has no clip state information because of which we ignore clip parameters set in rect clip and shape clip. We need to query and use encoders from EncoderManager to honour clip states in copyArea.
