rhi: gl: Have a way to state GL_TEXTURE_RECTANGLE is wanted
Added specifically to support the deprecated CVOpenGLTextureCache on
macOS, because Qt Multimedia still needs a way to use that when the
applications requests using OpenGL instead of Metal.
Follow what we did for GL_TEXTURE_EXTERNAL_OES, and add a flag that
simply makes all our glBindTexture calls use the
GL_TEXTURE_RECTANGLE[_ARB] target.
Pick-to: 6.2
