Subject: [PATCH v2 08/12] feat(vrr): allow for setting refresh rate if the
 internal display allows

For the Ally, we have a set of VFP that work to set the refresh rate.
They can also be used for VRR but gamescope does not currently allow for
it. Therefore, bypass some checks to allow it to work just for this usecase.

Subject: [PATCH v2 09/12] feat: add external option that now only lies to
 steam

Previously, there was a force-panel option that allowed for VRR.
However, this is no longer the case and VRR works fine.
This option still allows for scaling the display though. So, create a
variant of the patch that only does that.

Subject: [PATCH v2 10/12] fix(display-config): always fill in mutable refresh
 rates

Assume the user is not lying to us when they fill in dynamic_refresh_rates
and that gamescope will work with e.g., CVT, so accept it even if no
custom modeline generation has been provided.
