picom: switch to mainline with spring physics animations

Browse Source 
Update picom from dccsillag fork to colonelpanic8/picom spring-physics
branch, which adds spring physics animation support to mainline picom.

Spring curve syntax: spring(stiffness, dampening, mass, clamping)
- stiffness: spring constant (higher = faster)
- dampening: resistance (higher = less oscillation)
- mass: inertia (higher = slower)
- clamping: prevent overshoot (false for bounce effects)
