Subject: [PATCH] graphics: hide subscreen window from task bar and alt+tab
 list when in full screen (#690)

## Link to GitHub Issue or related Pull Request, if one exists
n/a

## Description of change
When booting in fullscreen, hide the subscreen from the alt+tab list and
from the task bar. Alt-tabbing to it does nothing, so this is just to
avoid confusion.

No change to windowed mode.

## Testing
Tested TDJ/SDVX/Popn. Didn't test Gitadora but it's probably fine..
