Subject: [PATCH] Bug 1795630 - Export MathML crashtests to WPT. r=emilio

This commit moves crash tests from dom/mathml and layout/mathml into
testing/web-platform/tests/mathml/crashtests/mozilla, trying to do only
minimal changes (i.e. use 'test-wait' instead of 'reftest-wait').

The exception is 400157.xhtml which uses special powers to trigger a
zoom changes. It could probably be tweaked to convert to a mochitest or
rely on a different dynamic change. However, this was testing a crash for
the `<mfenced>` element in nsMathMLmfencedFrame whose code has been
completely removed, so it's now hard to reproduce the original crash.
Also that makes the test no longer very useful, so we just remove it.
