Visor tint for cockpit views

Problem: it’s difficult to see the track because of glare from various surfaces in many weather conditions and times of day.
Proposed change: add the ability to cycle through various visor tints during a race or practice.
Implementation notes: this should be easy to implement as it should only require repurposing photo filters from ForzaVista. It’s important that the filters improve visibility from the cockpit views though. This is not just an aesthetic change.
