Add support for freeform windows in the Android editor

[SanekGamer007]

Describe the project you are working on

irrelevant

Describe the problem or limitation you are having in your project

Debugging is a bit clunky, especially with the parts of the editor being cutoff in the App-by-App mode.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Allows you to make the debug build open in a freeform window, allowing for easier debugging.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

When you press "play" the game will open in a freeform window instead of being by side.

If this enhancement will not be used often, can it be worked around with a few lines of script?

App-by-App is perfectly usable, but freeform in my opinion would be better.

Is there a reason why this should be core and not an add-on in the asset library?

Is this even possible to be an addon?
