Arsenal - Improve armor stat for medical

[LinkIsGrim]

When merged this pull request will:

• Title.
• Hide GForce stat for most uniforms, which was the code intention.

New stat isn't completely transparent, but it's less misleading (explosive protection is actually ballistic protection because it's armor, yikes).

IMPORTANT

• Title of this PR uses our standard template Component - Add|Fix|Improve|Change|Make|Remove {changes}.

V_PlateCarrierGL_blk is reported to be level IV and V_PlateCarrierSpec_blk to be level V.
However

["V_PlateCarrierGL_blk", "HitChest"] call ace_medical_engine_fnc_getItemArmor
returns
[78,20.252]
and
["V_PlateCarrierSpec_blk", "HitChest"] call ace_medical_engine_fnc_getItemArmor
return
[24,19.8021]

Imo that doesn't feel right.
