Implemented Controller Hotkeys (#111)

Implemented Controller Hotkeys

Added controller hotkeys
Added guide button support for XInput and winkey

The hotkey configurations can be found in HID -> Display controller hotkeys
If the Xbox Gamebar overlay is enabled then use the Back button instead of the Guide button.

- Fixed hotkey thread destruction
- Fixed XINPUT_STATE by padding 4 bytes
- Added hotkey vibration for user feedback
- Replaced MessageBoxA with ImGuiDialog::ShowMessageBox
