[REQUEST] Display/graphics settings for desktop builds

[liana-p]

Is your feature request related to a problem? Please describe.
Most games have display settings to toggle fullscreen mode, change window size etc. Narrat games should have this by default for newly created projects

Describe the solution you'd like
Electron already has all the functionality to use fullscreen, windowed, borderless etc as far as I know.

To make this work, we'd need to update the template to have functions in the electron config that can handle changing display mode appropriately, and add a way for the engine to call those electron functions if present.

Then we can add those options in the game settings.

Games should also be able to configure in settings whether they want to allow players to change the settings.
