World: extract getBlockCollisionBoxes() from getCollisionBoxes()

Browse Source 
closes #6104

This function has been a footgun for anyone using it, since it also returns entity AABBs by default.
In all core use cases, this functionality was disabled, and we were paying a needless (admittedly micro) performance penalty for passing the extra useless argument and useless condition check.
