UI - Make Speed Indicator Independent of Stance Indicator

[LinkIsGrim]

Is your enhancement related to a problem?
Speed Indicator added in 3.14 is a sub-control of the Stance Indicator, which means its visibility is subject to the mission's difficulty settings having the stance indicator enabled. This also results in the Speed Indicator not being shown unless there's been a recent stance change if the stance indicator is set to fade-out.

Solution you'd like:
Tie the Speed Indicator to another class of RscInGameUI (RscUnitInfoSoldier seems most appropriate), or make it its own class entirely, like Advanced Fatigue's Stamina Bar.

Alternatives you've considered:
It's possible to disable the Stance Indicator via Selective UI while having it enabled in difficulty settings. This doesn't account for the fade-out possibility.

Additional context:
The medical feedback indicators (fractures, blood volume, splints, tourniquets) suffer from the same issue.
