fix: CompositeCollider behavior affecting TileMap w/Realistic Solver (#3322)


Fixes issue where the realistic solver gets confused with TileMaps mentioned in the discord https://discord.com/channels/1195771303215513671/1320140196372676692

The issue causes massive overcorrection because it _appears_ to the solver that the collider in a composite is further away from the contact than it actually is.

In the fix we shift the collider local side by the offset (which is what is used in composites to position relative to the transform). This gives an accurate pos for the contact point
