1. Add a loop flag for CMDQ packet struct.
CMDQ helper will use a loop flag to mark CMDQ packet as lopping command
and make current command buffer jumps to the beginning when GCE executes
to the end of command buffer.

2. Add a looping task handle flow in irq handler.
GCE irq occurs when GCE executes to the end of command(EOC) instruction.
If the CMDQ packet is a loopping command, GCE irq handler can not
delete the CMDQ task and disable the GCE thread.
