Add option for showing the overlay behind the menu (#13360) 
* Add option for showing the overlay behind the menu

This commit lays the groundwork for this option. Support for this option
in the video drivers themselves is going to be added in later commits.

* gl1: Add overlay behind menu support

* gl2: Add overlay behind menu support

* gl3: Add overlay behind menu support

* vulkan: Add overlay behind menu support

* ctr: Add overlay behind menu support

* d3d9: Add overlay behind menu support

* d3d10: Add overlay behind menu support

* d3d11: Add overlay behind menu support

* d3d12: Add overlay behind menu support

* CHANGES.md: overlay behind menu
