[1.21] Include actual y level for anchor tooltips

[unilock]

This PR adds the actual y level to the "distribution" tooltips that lack it, based on the client's current dimension. As discussed in #16, a note is also added to relative tooltips that the values only apply to the current dimension.

Maybe the note should also mention that the current dimension may not contain every feature? It feels a little long already...

Examples:

( Hopefully this can be cherry-picked to 1.20.1 as well? :p )

Hm, it is a little busy, perhaps the relative values could be switched out for absolute (for the current dimension) when the shift key is held? This could also apply to the values on the "graph". Also, the default could be configurable in the config file.

Sorry for continuing to request changes on this PR, after this many months one is bound to have new ideas of how best to implement things :P

As for the 1.20.1 port, I've moved to a new merge-down workflow (inspired by EMI's) so any changes will naturally get propagated down to the backports (including 1.19.2).

I've implemented showing the height values for the current dimension only when shift is held - however, it appears that it's necessary to manually refresh the recipe's display while holding shift (e.g. by switching recipe pages in EMI) to get the values to update. I am not sure how to fix this :p

[unilock]

The config has been implemented as well. I suppose the distribution graph tooltip should also be updated to indicate that holding shift will change which height values are displayed, but the tooltip is quite long already...
