Fullscreen's "Size Setting" is throwing an error when not null

[Visssarion]

Versions tested on: 3.2.1, 3.2.0

Setting "Size Setting" inside of Fullscreen Setting Resource results in:

• Error Trying to assign value of type 'int' to a variable of type 'String'. when running the scene
• Error Trying to assign value of type 'bool' to a variable of type 'String'. when flipping the fullscreen switch
  on a line 29 of setting_display_fullscreen.gd

Minimal Reproduction Demo:

Also, fullscreen setting uses MODE_FULLSCREEN, which causes 1px border around application. Using MODE_EXCLUSIVE_FULLSCREEN instead fixes it. (Maybe there could be an additional setting in the setting resource?)

From here:

• This is intentional and done to ensure multiwindow interface works in fullscreen (MODE_FULLSCREEN is only intended for GUI apps like Godot editor itself, not for games).

• For everything else, use MODE_EXCLUSIVE_FULLSCREEN (naming is bad, this mode is fully equivalent to 3.x MODE_FULLSCREEN).

• I'm pretty sure it is the same in 4.2 (and other 4.x), but border was always black, now it's using clear color from project settings.

I've changed the issues you've mentioned. Everything should be fine in the latest push to the 3.2 branch.
