Use internals for getting block/entity countstimings/use-internals

For a long time I've been meaning to move some of this logic internally
as this would allow us to avoid hitting systems like block state snapshots
which can create issues as many of the spigot implementations of this
stuff are increasingly broken, leading to unexpected crashes during ticking,
even if the API cannot properly interact with these such states/items,
it's generally more preferable to not crash the server in the course,
and just let those interactions fail more gracefully.
