Memory cleanup and optimizations

- Returns an empty list when there's not registered plugins, thus preventing the creation of spurious iterator objects

- Inline `Godot#getRotatedValues(...)` given it only had a single caller. This allows to remove the allocation of a float array on each call and replace it with float variables

- Disable sensor events by default. Sensor events can fired at 10-100s Hz taking cpu and memory resources. Now the use of sensor data is behind a project setting allowing projects that have use of it to enable it, while other projects don't pay the cost for a feature they don't use

- Create a pool of specialized input `Runnable` objects to prevent spurious, unbounded `Runnable` allocations

- Disable showing the boot logo for Android XR projects

- Delete locale references of jni strings
