GL: Fix default framebuffers being bound using srgb

Default backbuffers needs not to be bound with sRGB encoding
enabled. This works when using `GPU_framebuffer_restore` but
using `GPU_framebuffer_bind` would trigger the wrong behavior.

This fix T81969 UI turns whiteish when playing video sequence
based on a scene and moving in the image editor after saving
