L4D2VR 2.0.7 - arms on the right shoulders, crowbar/axe held at the handle, Pavlov toggle grip, no hand switching

Includes everything from the 2.0.x test builds (OpenXR-only; see the 2.0.0 notes for the Proton/launch requirements). Updating from 1.2.2: read the 2.0.0–2.0.6 notes for the full list of changes.

Fixes in 2.0.7

• The arms no longer come from the wrong shoulders after you turn around in your room: the arm IK's shoulders now follow the direction you face (with the same comfort cone as the first-person body), not only the stick-turn direction.
• The crowbar and fire axe are held at the handle end instead of the middle of the bar/shaft; the Ancient Dungeon-style swing lag still pivots at your hand.

From 2.0.6

• Magazine well, bolt/pump, foregrip, flashlight, muzzle and scope follow the drawn gun (reloads seat at the visible well again).
• Right hand sits on your real hand by default.
• No hand switching of held items; Pavlov toggle grip (squeeze to take, squeeze again at the holster to put away, elsewhere to drop). GripToggle=false restores hold-to-grip.
