chore: proper keybind handling and better input blocking system

[UndercoverGoose]

• Adds mixins to process key/mouse inputs right before Minecraft handles them
• Adds InputBlocker to cancel the events received by the mixin when activated
• Adds TickHelper (should probably be TickScheduler?) for scheduling events to occur after an amount of ticks
• Wraps the native KeyBinding to allow for modules to determine the physical state of the key
• Adds methods to control virtual key state even while physical inputs are blocked:
  • Sending a single press
  • Holding or releasing the key
  • Holding or releasing for a specific number of ticks
• Updates KeybindWidget and modules that reference it to use this system
• Updates modules that reference KeyBindingAccessor or KeyboardInputMixin for old input blocking
