Refactor the collision system, various improvements to how collision fixes is handle, more fixes (again).

This is my second attempt, since I screw up the last one :) yay! so.

Changes:

• Deleted grass path collision fix since as of 1.21.71, this block collision is the same as java edition.
• Deleted the logic for stepping in correctPosition, since this caused many issues (already discuss in Discord).
• Refactor code inside correctPosition, make it little bit more readable.
• correctPosition now no longer return true/false, as in the original code this method always return true.
• Now for collisions fixes like trapdoor/door/glass pane/iron bar. Properly calculate the distance we actually need to move player position by instead of just moving it by a certain value, as the player could actually just clip less than that value, causing the position get offset more than it needed to.
• Fixed chest collision by moving player position down, resolve: Incorrect chest collision on bedrock #3277 and resolve Damage with flooded chests #4955
• Fixed setback when hitting your head to an lantern
• Fixed setback when moving into an scaffolding due to collision differences (can be shown in getting stuck #5787, however the player will fall through the scaffolding unlike java where they can work on it (bedrock behaviour)).
• Also fixed some other small issues caused by my last PR.

I wonder if the collision fix for trap doors fixes #2951?

Let me know once this is ready for review & I'll do testing on my end

Nope it won't since as of now we're doing Don't correct position if controlling a vehicle, some changes have to made on the PR if we wanted to fix that.

Edit: Can't reproducible as of latest also.
