android: Implement quick configure for external controllers

[OpenSauce04]

Rebased from #283 by @newhinton

This PR implements a fast-button-mapper.

The user can now click the Auto Configuration setting in the gamepad-section, which will open a new dialog.
This dialog will then iterate over the available buttons, where the user can quickly press a button on the gamepad without having to pre-select which button this press should be assigned to.

This PR is currently a work in progress.

Todo's:

• Fix Analog Axis assignment
• Change strings to a consistent namingscheme, also figure out how this should be called
• Evaluate MotionBottomSheetDialogFragment so that we don't have code duplication like now
• Clicking the Next button seems to not actually skip to the next button the first time you press it, instead duplicating the button into both the current and previous button slots. It must be pressed a second time to actually progress to the next button
• Closing the prompt before reaching the end still applies all previously selected binds. The binds should only be applied if the process is completed
• Using dpad button binds is redundant if axis binds were detected. The button binds should be skipped over if axis binds are applied successfully
