GLES2Dbg: add EXTEND_AFTER_CALL_Debug_* macro and improve protocol

To allow auto generate of Debug_glReadPixels function.
Also added AfterGeneratedCall messag type, and client override
 of expectResponse for improving protocol.
Also implemented callers for client to get shader/program iv & infolog
