fix: quit properly in simpleFullScreen mode

[codebytere]

Description of Change

Fixes #13135.

Since borderless windows or windows without titlebars doen't have a close button, performClose: won't work. Therefore, we instead want to use the close method. However, this method doesn't call windowShouldClose: on the window's delegate so we manually must call it.
