Move snapping responsibility to IBeatmap

Browse Source 
Seems `EditorBeatmap` already implements a different kind of `SnapTime` from `IBeatSnapProvider`, so method names here aren't great.

This is very similar to what https://github.com/ppy/osu/pull/12558 is doing, so may need to do some duplicate resolution later, especially surrounding `ClosestBeatSnapDivisor`.

Worth noting that this change makes 1/7, 1/5, etc unsupported for now, as we now rely on `BindableBeatDivisor.VALID_DIVISORS`.
