Android port of the Godot Editor

These set of changes focus primarily on getting the core logic and overall Godot Editor UI and functionality up and running natively on Android devices.
UI tweaks / cleanup / polish, as well configuration for Android specific functionality / restrictions will be addressed in follow-up PRs iteratively based on feedback.
