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.

Now the audout and audren update rates are tied to the sink status stalling is no longer necessary.

Waiting on the host side is inaccurate and leads to desyncs in the event of the sink missing a deadline that require stalls to fix. By waiting for the sink to have space before even starting rendering such desyncs can be avoided.

qt: Fix log softlock

memory: rename global memory references to application memory

service: nfp: Add plain amiibo support

This avoids the need to stall if the host sink sporadically misses the deadline, in such a case the previous implementation would report them samples as being played on-time, causing the guest to send more samples and leading to a gradual buildup.

tests: mark integer literals as unsigned

container_hash: use climits

CMakeLists: Use boost 1.79.0 instead
