stylo: Bug 1389429 - The interpolations of rotatex and rotatey are not correct.
These patches fix the potential divided-by-zero issue on non-normalizable
direction vector of rotate3d, and the interpolation between rotatex/rotatey and none.

Let's see the example: "rotatex(360deg)" to "none".
While we do interpolation between "rotatex" and "none", the original code
path is:
1. Build an identity transform for none and always use (0, 0, 1) as the
direction vector, i.e. Rotate(0, 0, 1, 0deg).
2. Do interpolation between rotatex (i.e. Rotate(1, 0, 0, 360deg)) and
Rotate(0, 0, 1, 0deg). Because their direction vectors are different,
so we do matrix decomposition/interpolation/recomposition on both
functions. The problem is, matrix decomposition makes the 360deg
disappear, so it looks like "rotatex(0deg)".
3. Obviously, we are trying to interpolate from rotatex(0deg) to none, so
the interpolated matrix is always an identity matrix.
I think rotatex, rotatey, and rotatez are special cases which should
really rotate according to the angle, so we should build the identity
transform for them according to the normalized direction vector, and so we do
interpolation on the angle, instead of converting them into matrix.
Replacing build_identity_transform_list() with
add_weighted_transform_lists(list, list, 0, 0) might be another solution;
However, I didn't do that because build_identity_transform_list() is
much simpler.
End TreeBuilder's reliance on DOM.

This PR accounts for the fact that the namespace table is only needed in
`NestedRuleParser`, and only for style rules, in order to simplify the setup and
be able to fix a few bugs wrt parsing of invalid rules.

style: Replicate the list of stylesheets on the layout thread.
This is a patch that unifies a bit how Gecko and Stylo stylesheets work, in
order to be able to eventually move the stylesheets into the stylist, and be
able to incrementally update the invalidation map.
This is on top of #18113

Use fewer allocations when reporting Gecko errors.
Avoid some unnecessary string allocations when extracting meaningful values out of CSS parser error messages.

We need to use enum instead of Either since we can't interpolate stroke-* between
unitless length and unit length(e.g. '5' -> '10px').
This coomit make following:
* Introduce SVGLengthOrPercentageOrNumber on computed and specified values.
* Make SVGLengthOrPercentageOrNumber animatable.
* Make stroke-dasharray not-accumulate.
