Gather the conditions to return from the VCPU loops in nvmm_return_needed(),
and use it in nvmm_do_vcpu_run() as well. This fixes two undesired behaviors:
- When a VM initializes, the many nested page faults that need processing
could cause the calling thread to occupy the CPU too much if we're unlucky
and are only getting repeated nested page faults thousands of times in a
row.
- When the emulator calls nvmm_vcpu_run() and immediately sends a signal to
stop the VCPU, it's better to check signals earlier and leave right away,
rather than doing a round of VCPU run that could increase the time spent
by the emulator waiting for the return.

Register NVMM as an actual pseudo-device. Without PMF handler, to
explicitly disallow ACPI suspend if NVMM is running.
Should fix PR/55406.
