CS2 update: smoother weapon animations

TL;DR A small patch from Valve. Weapon switch and reload animations at extreme angles should no longer pop or glitch. Bots in the official Retakes mode find their way around the map better, and DX11 players shouldn't run into rendering hangs anymore. Plus general stability and performance improvements.
