commit 36670a32fb24c76cbba10511911f17339204d2c9

Roll in new version of WPT tools

https://github.com/w3c/web-platform-tests/pull/10985 changed lint.py
and wpt-importer is now failing because of it:
https://ci.chromium.org/buildbot/chromium.infra.cron/wpt-importer/17652

chromium.patch did not apply cleanly, so the changes had to be rebased
on the new wpt version.	This was much easier within the	wpt repo
itself, so the patch is	changed	to apply within	the repo.

The importer started to roll again: https://chromium-review.googlesource.com/c/chromium/src/+/1064011

This issue is fixed.

However, it looks like the import will fail because of some other issue (likely issue 839183). Let me take a look.
