Make rounded collision edges only apply to Mario

[FazanaJ]

My own testing has lead me to find that rounded collision edges are almost twice as slow as vanilla SM64's collision. While there's time to be found in the former, I still recommend having it be made so only Mario will actually do this, because it's a waste of processing for other objects that will not benefit at all.

Should this be configurable per-object? It helps with large object hitboxes.

If it's a tangible benefit then yes, an object flag would instead suffice.

If you do it that way make sure the default is NOT having round corners and the object flag ENABLES it
