This PR reduces the number of sync loads occurring on any teleport caused by essentials.
Fixes#2861Fixes#2287Fixes#3274Fixes#3201Fixes#2120
Before this PR, essentials would get a block multiple times causing sync loads to check if it was safe to teleport to. Now, the target block's chunk if fetched async with PaperLib and passed along to `LocationUtil#isBlockUnsafeForUser` (which internally calls other LocationUtil methods what that chunk object) resulting in the chunk only loading once, off the main thread. The only operations remaining on the main thread is `LocationUtil#getSafeDestination`. This is due to the method's recursion which would be a pain to move async. **However:** since the chunk was already loaded async, `LocationUtil#getSafeDestination` most of the time won't cause sync chunk loads. The only time it would cause sync chunk loads is with an unsafe location near a chunk border.
