Bug 1636693 [wpt PR 23495] - Update menclose help and explains better how tests work in MathML core, a=testonly

Automatic update from web-platform-tests
Update menclose help and explain better how tests work in MathML core (#23495)

No consensus have been reached on the future on menclose so far but this
element has been the source of confusion so the current draft text has
been removed from MathML Core and put in a separate pull request:

w3c/mathml-core#24

This PR updates the WPT tests accordingly:

* Actual tests for menclose are renamed "tentative" and refer to the
  pull request above, so that it becomes clear they are not definitive yet
  and browsers are free to ignore them.

* Tests for mrow-like are now referring to MathML3
  https://www.w3.org/TR/MathML3/chapter3.html#presm.menclose
  They are still valid because unknown elements are treated as mrow-like
  in MathML Core.

* Tests for removed legacy features are obviously still valid too.
  Again, the documentation is updated to refer to MathML3
  https://www.w3.org/TR/MathML3/chapter3.html#presm.menclose
