Some games have very tight scheduling requirements for their audio which can't really be matched on the host, adding a constant to the reported value helps to provide some leeway.

x64: Make use of waitpkg instructions for power efficient sleeps

Co-Authored-By: liamwhite <liamwhite@users.noreply.github.com>

For CPUs that support tpause, this should result in significant CPU power savings over thread yield in this spin wait.

MicroSleep allows the processor to pause for a "short" amount of time (in the microsecond range). This is useful for spin-waiting that does not require nanosecond precision.
This uses the new TPAUSE instruction introduced on Intel's newest processors as part of the waitpkg instructions. For CPUs that do not support waitpkg instructions, this is equivalent to yield().

waitpkg introduces 3 instructions, UMONITOR, UMWAIT and TPAUSE.
