Now that we can select a workload profile dynamically when
we submit work, it's best to default to the bootup
default workload profile. Defaulting to other profiles
prevents some power management features from kicking in
during idle periods. Once all jobs have finished, the
workload profile will automatically move back to default
bootup for max power savings.

Add helpers to switch the workload profile dynamically when
commands are submitted. This allows us to switch to
the FULLSCREEN3D or COMPUTE profile when work is submitted.
Add a delayed work handler to delay switching out of the
selected profile if additional work comes in. This works
the same as the VIDEO profile for VCN. This lets dynamically
enable workload profiles on the fly and then move back
to the default when there is no work.

Current kfd driver has its own PASID value for a kfd process and uses it to
locate vm at interrupt handler or mapping between kfd process and vm. That
design is not working when a physical gpu device has multiple spatial
partitions, ex: adev in CPX mode. This patch has kfd driver use same pasid
values that graphic driver generated which is per vm per pasid.
These pasid values are passed to fw/hardware. We do not need change interrupt
handler though more pasid values are used. Also, pasid values at log are
replaced by user process pid; pasid values are not exposed to user. Users see
their process pids that have meaning in user space.

The stub execution uses the somewhat new close_range and execveat

close_range call is more about stub process hygiene rather than safety
(and its result is ignored).
Replace both calls with a raw syscall as older machines might not have a
recent enough kernel for close_range (with CLOSE_RANGE_CLOEXEC) or a
libc that does not yet expose both of the syscalls.

The lint has been added by Yutaro Ohno, based on feedback from the kernel

Clippy reports a few cases in the kernel, apart from the one already
fixed in the commit above. One is this one:
error: doc list item overindented
