ameerj 5213f70230 texture_cache: Blacklist BGRA8 copies and views on OpenGL 
In order to force the BGRA8 conversion on Nvidia using OpenGL, we need to forbid texture copies and views with other formats.

This commit also adds a boolean relating to this, as this needs to be done only for the OpenGL api, Vulkan must remain unchanged.
