Misc editor tweaks and polishes:

- Using a bucketized approach to select the editor scale in order to avoid too high values
- Add default app dimensions: used on Android devices with free floating app windows to set the default app frame
- Add ability to launch the Game window in an adjacent frame when in multi window mode

(cherry picked from commit 6f7ec7f723)
