ENT-11202, ENT-11335, ENT-11305: TOC bug-fixes

[mineralsfree]

Improvements:

1. Id generation for section headers (copied hugo behaviour of resolving same ids: id, id-1, id-2, id-3).
2. Ignore h5, h6 when creating TOC.
3. Set active link after page is loaded.
4. TOC autoscroll calculates each TOC item height to move the container.

@mineralsfree remember to bring this to 3.21 and Alvaldi.

The changes look good to me but it seems like this could be split up into a few comments with explanations of what problem they fixed and how?

@craigcomstock we discussed this in person; a bit hard to untangle, some of the changes probably won't work separately (and so it doesn't make so much sense to split into separate commits). We considered to merge all the tickets into one ticket, but I said it was okay to do it like this. Also, keeping it together will probably make it quite a bit easier when cherry-picking.

The commit message could use a bit more words though, for example a list of what issues were fixed, instead of relying only on the tickets.

I've updated the PR description. Will make better commit messages next time
