Origin offset fixes
https://github.com/immersive-web/webxr/issues/567 was closed out. We were computing offset spaces of already-offset spaces incorrectly, but otherwise our math is correct. I improved our comments around this with more math, so I never have to do this math again.
Chrome's math isn't, which is why we fail some tests around this: https://bugs.chromium.org/p/chromium/issues/detail?id=1030049 . I'm planning to wait for them to fix and upstream the tests, I've already verified that we pass the corrected test.

Fixes an issue where DOMString::is_valid_floating_point_number_string
was returning true for strings that began with whitespace characters-
TAB, LF, FF, or CR. Also added a unit test to cover this since the
corresponding web-platform-tests are incomplete.
Replaced catch-all with explicit case for inputs that do not have
a value sanitization algorithm. This should prevent us from
forgetting to implement a sanitization for an input, since they
must all be accounted for in the match expression.
I see atom dropping code generated in release builds for stuff like dropping the
"class" atom here:
https://searchfox.org/mozilla-central/rev/4df8821c1b824db5f40f381f48432f219d99ae36/servo/components/style/gecko/wrapper.rs#592
That is silly, and I hope making Atom be able to be used in const context will
help the compiler see that yeah, we're not doing anything interesting and the
atom shouldn't get dropped.
It also allows us to get rid of a few lazy_static!s, so we should do it anyway.
In order to accomplish this, compute the offset into gGkAtoms manually instead
of going through the static_atoms() array and then back to the byte offset.

When zoom is disabled, we still count it, but with the current code the testing
function will throw instead of returning the right value, which means we'd fail
layout/style/test/test_use_counters.html.

Some of the stuff, in particular inside GeckoBindings stuff should be
refactored to be less ugly and duplicate a bit less code, but the rest of the
code should be landable as is.
Some invalidation changes are already needed because we weren't matching with
the right shadow host during invalidation (which made existing ::part() tests
fail).
Pending invalidation work:
* Making exportparts work right on the snapshots.
* Invalidating parts from descendant hosts.
They're not very hard but I need to think how to best implement it:
* Maybe get rid of ShadowRoot::mParts and just walk DOM descendants in the
Shadow DOM.
* Maybe implement a ElementHasExportPartsAttr much like HasPartAttr and use
that to keep the list of elements.
* Maybe invalidate :host and ::part() together in here[1]
* Maybe something else.
Opinions?

At first I thought this was going to enable simplifications in the selector
parser (to simplify the attribute selector setup), but I couldn't end up
shrinking the layout enough.
However this should help with bug 1559076, which returns Option<Atom>, and it
was easy to write.
