Leaves distance update event

Is your feature request related to a problem?

It would be nice to have this feature to prevent / change the distance of leaves when their distance is updated internally.

This allows for making other blocks behave like leaves and logs. One example is if you want a note block with a specific state to act like a log. Then when the event is called, you can check the neighbors and set the leaves distance to 1 if one of the neighbors is the noteblock. This allows texture packs to be used to make custom logs without having to deal with all the different events that can cause a leaves distance to be updated, such as placing a block, breaking a block, pushing a block with a piston, etc.

Describe the solution you'd like.

I made a PR for the event which I will link to this issue.

Describe alternatives you've considered.

An alternative is to use the BlockPhysicsEvent, but that is a general-purpose event that also might not get called every time the distance of leaves are updated.

Start with linked pull request #12753 and trace how the proposed event relates to internal leaves-distance updates. Compare it with BlockPhysicsEvent and the listed update causes, then verify that the new event supports changing leaves distance for each relevant update path.
