Fixed BTR twerking on steep slopes (!142)

Browse Source 
In the end, Kaeno's fix by changing the main client collider's layer to `HighPolyCollider` is the only way I could fix it.

Also made changes to avoid unnecessary physics collisions between other BTR colliders; these physics collisions can cause FPS drops especially for lower end PCs so this should provide a slight performance gain for them.

I left in the commented-out collision debugger script I made to log collisions in case it's useful for future debugging purposes.
