InputCommon:QuartzKB&M: Use KVO to watch window position

[TellowKrinkle]

CGWindowListCreateDescriptionFromArray would send a request to WindowServer and block until it got a response. This had two issues:

1. The call took ~200µs on average. Dolphin's main emulation thread seems to call UpdateInput() about 5 times per frame during Wii emulation, wasting 1ms per frame
2. Since you're now waiting for WindowServer to get back to you, what if it just happens to be busy when you made your request? About 5% of calls take >1ms, some upwards of 2ms.

Changes QuartzKeyboardAndMouse to use a KVO observer on the window to update a position variable under a mutex.

Also modifies QuartzKeyboardAndMouse to calculate mouse coordinates relative to the main view, rather than the entire window (which includes the window's titlebar).

LGTM.

I almost wrote that this PR fixed the horrible frame pacing on Intel Macs, then I remember I didn't test Dolphin since updating to Ventura RC and tested the a version before this PR.

Actually It was Ventura that fixed the frame pacing issue, I guess there are some nice improvements to Metal and AMD drivers, now Dolphin it's smooth as butter even on Intel Macs!

Anyway, a big thanks for all the Ubershaders and latest improvements that made this stutter free experience possible on Macs too!

In that case, I wouldn't be surprised if you test #11028 and run with --config=Graphics.Settings.MTLUsePresentDrawable=1 (or by adding MTLUsePresentDrawable=1 to GFX.ini) (note: will prevent fast-forward), that would probably fix it on pre-Ventura as well (though for Metal only).

Side note: Does fast forward still work on Ventura?

Fast forward works on Ventura.
