[BUG]: PCSX2 incorrectly limits FMV speed

[ghost]

Describe the Bug

PCSX2 limits the frame rate according to the game's region, but not its video's speed, resulting in freezes in both #11023 and #4886 as well as incorrect audio in #3603 all because videos were playing faster than they were designed to. Likely also impacts #5192, #7427 and #1634 but I haven't tested those yet.

Reproduction Steps

Expected Behavior

For PCSX2 to automatically detect the FMV speed and set it as the frame rate limit for as long as the fmv runs. My hypothesis is that counters[i].rate = 2; has three states: 1, 2, 4 under different circumstances.

We don't limit the frame rate. We provide the sync clocks and the game controls the rest.
