PassThroughInputManager needs to receive initial state from parent

[smoogipoo]

In the case that UseParentInput is set to true, it may not apply the full parent state when handling input.

E.g.

1. Enter a mania beatmap without auto.
2. Hold ctrl while in PlayerLoader just before gameplay.
3. Attempt to press Ctrl+(-/+)

Expected: The scroll speed should change.
Actual: Because modifier keys specifically are not propagated on repeat, the mania input manager will handle a -/+ keypress without state.Keyboard.ControlPressed being true.
