Subject: [PATCH] Removed logic forcing vsync on if setting it off fails

The platforms that needed this (Windows Phone and Windows RT) are no longer supported, and if this is needed in the future it should be done at the renderer level, not here.

Fixes https://github.com/libsdl-org/SDL/issues/12475
