Latte: Enable colorbuffer optimization if gfx packs are aware

Browse Source 
The optimization for colorbuffer resolution introduced in PR #706 is now enabled. This optimization changes the resolution of certain framebuffer textures, which may conflict with the texture resolution rules set by some graphic packs. As a result, if a graphic pack that specifies texture resolution rules is in use, the optimization will automatically be turned off to prevent any issues.

To circumvent this, graphic packs can now include the setting "colorbufferOptimizationAware = true" in their rules.txt. This setting indicates that the pack has been updated to handle the resolution changes introduced by the optimization. Cemu will allow the optimization to remain enabled if resolution packs have this flag set.
