In interrupt context, write dbg_ev_file will be run by work queue. It
will cause write dbg_ev_file execution after debug_trap_disable, which
will cause NULL pointer access.
v2: cancel work "debug_event_workarea" before set dbg_ev_file as NULL.

The MES cached process context must be cleared on adding any queue for
the first time.

For proper debug support, the MES will clear it's cached process context
on the first call to SET_SHADER_DEBUGGER.

This allows TTMPs to be pesistently enabled in a safe manner.

MES can concurrently schedule queues on the device that require
exclusive device access if marked exclusively_scheduled without the
requirement of GWS.  Similar to the F32 HWS, MES will manage
quality of service for these queues.
Use this for cooperative groups since cooperative groups are device
occupancy limited.

Since some GFX11 devices can only be debugged with partial CUs, do not
allow the debugging of cooperative groups on these devices as the CU
occupancy limit will change on attach.

In addition, zero initialize the MES add queue submission vector for MES
initialization tests as we do not want these to be cooperative
dispatches.
