stylo: Bug 1387990 - Fix the interpolation of 2d matrix.
Write a 2d matrix decomposition for Gecko, so the visual results and test results
could match those in Gecko. In long-term, we should let Gecko follow the spec, so we
can drop the redundant implementation.

The implementation of 2d matrix decomposition in Servo matches that in
spec, but its result is really different from that in Gecko, so the
visual results on the main thread and on the compositor thread are
really different and we got many test failures. Therefore, let's write a
different algorithm of decomposition of 2d matrix for Stylo, and keep
the original one for Servo.
The output of new implemented 2d matrix decomposition is a Decomposed3DMatrix,
so we can reuse the interpolation and re-composition code. (Just like
what we do in Gecko.)
Don't cache style data if the element has running animations.

This will allow tracking whether there have been only additions to the
stylesheet set, and in that case don't destroy and completely rebuild the
invalidation map.

Also add a few comments and similar about pending invalidation work, and avoid
passing a device in script, since the work it performs scanning the stylesheet
is just thrown away in the `flush_without_invalidations` call.

Add ComputeSquaredDistance trait for SvgLengthOrPercentageOrNumber
<!-- Please describe your changes on the following line: -->
This is a PR for https://bugzilla.mozilla.org/show_bug.cgi?id=1387986
This patch will add ComputeSquaredDistance trait for SvgLengthOrPercentageOrNumber in order to calculating distance between LengthOrPercentage and Number.

There are already these tests in dom/smil/tests of gecko, this PR will enable these tests.

Currently, Servo uses ComputeSquaredDistance derive for
SvgLengthOrPercentageOrNumber, so servo can't calculate between
LengthOrPercentage and Number.
This PR will allow calculating these value.
style: Keep dirty bit invariants during invalidation.
There's the question of whether should we be recursing into the invalidation
code for elements without data... Probably not, but that's a somewhat more
risky change.

make sure proper frame tree is sent when iframes change
We ran into a hittest issue because the frame tree was not correctly updated after #17425.
The frame tree should be updated on tab change (via send_frame_tree) or when the frame sub tree changes and it's the active one (via update_frame_tree_if_active).
