axe-core: update and evaluate all the enabled checks

[paulirish]

axe 4.0!

also remove video-description, etc. #10128

---

see last times we did this:

• evaluate new axe audits for inclusion · Issue #7127 · GoogleChrome/lighthouse
• Clean up aXe audits · Issue #6169 · GoogleChrome/lighthouse

Let's double check that #11649 is fixed by updating to axe 4 once this is done, if not we can reopen that issue :)

yayyyyy this gonna be fun

maybe will add a new build step to transpile this to commonjs, keep in third_party

actually this would be better: let's merge #11442, so we don't import this file directly from source.

for importing es modules into commonjs, need to use import(), not require():

(this can be annoying, however, because then it has to be async)
