This uses the current content being displayed to determine whether or not to engage an HDR colorspace.
Add VFP timings for the non-VRR frame limiter, and enable content_driven HDR mode to workaround lack of Steam support for backlight control while the Go 2's panel is outputting PQ content. This can be re-assessed when Steam supports internal panels with HDR that behave less like the Steam Deck OLED when it comes to brightness adjustment.
