Add setting to control the window used to run the project for the Android editor

The follow options were added to the (new) `run/window_placement/android_window` editor setting:

- `Same as Editor`: run the project in the same window as the editor
- `Side-by-side with Editor`: run the project in an adjacent window to the editor
- `Auto`: choose how to run the project based on the device screen size
