script: ASUS ROG Ally + ROG Ally X display configuration

This introduces a display configuration for the ROG Ally and ROG Ally X handhelds. These devices feature the same 1920x1080p panel, which supports VRR and has a range limit of 48-120Hz in the EDID. I tested this configuration on two separate units: * ROG Ally - SteamOS Main 20240919.1002 with kernel 6.8.12-valve2-1 * ROG Ally X - SteamOS Main 20240919.1002 with kernel 6.11.2 Both function exactly the same throughout multiple games with the entire refresh rate slider within Steam.
