feat: FPS Limiter (#1446)

* Add interpolation frame rate cap

* wip: reworked framelimiter

Based on my testing this is a bit more stable in frametimes.

* wip: efficiency improvement + windows build fix

Significantly improve efficiency by using a hybrid approach.

* wip: UI changes

* wip: end frame AFTER limiting

* wip: remove unused include

* wip: minor ui code change

Makes it easier to remove/add presets

* Simplify Limiter UI

- Change enableFrameInterpolation to an enum with off/capped/unlimited values
- Simplify the UI to use 2 settings (unlock framerate + a max value entry)

* wip: slight limiter simplification

* wip: implement review suggestions

* wip: fix syntax error

* wip: revert enum order + replace old checks

* Fix compile error
