Ensure avoid checking PrimaryFrame before IsHostIsSlot for next tabbable

In GetNextTabbableContentInScope we iterate over content, trying to find
the next tabbable content within the scope. With the next peice of
iterable content we first check if it is IsInNativeAnonymousSubtree and
if it has a PrimaryFrame, and if so check that frames tabIndex. If the
element does not have a frame we then check the host/slot tabindex.
Finally if it's not a host/slot we check the primary frame (again).

This means for slots with a display:contents value, they'll have no
frame and they'll drop to the next condition (IsHostIsSlot), however
for slots with a frame (e.g. display:block) they'll use the frames
tabIndex value.

For a slot element with display:block this means we're reliant on the
primary frame's focusability, but this is an incorrect flow of logic
because it means that the slot with display:block is skipped - one such
element exists: the ::details-content pseudo.

By simply removing this check, and letting the else block resolve the
primary frame's tabIndex, we can correctly ensure ::detils-content
children can be focused.

Exclude anchor() and anchor-size() functions from MISU

These functions can become invalid at computed value time, even though
they are not substitution functions. MISU [1] is not able handle this,
so we just exclude those values.

[gap-decorations] Interpolation with repeaters for *-rule-color

This CL implements Interpolation for *-rule-color for repeaters.

In order to handle repeaters, we add a new InterpolableType
InterpolableGapDataRepeater which handles interpolation for repeaters
by essentially keeping a member InterpolableList of the values in the
repeater and interpolating those individually through that type.

The overall structure of interpolation for gap decorations will be as
follows:

CSSGapLengthListInterpolationType handles interpolation for
GapDataList We then hand off the actual interpolation with an
InterpolableList of InterpolableLength,
InterpolableGapDataRepeater (which itself contains an
InterpolableList of InterpolableLengths) and InterpolableColor.

InterpolableGapDataRepeater is templated, in order to handle for
interpolation for column/row-rule-color as well as width.

For now we are implementing mirroring the behavior of grid-template
interpolation (which can be a list of values with repeaters), in which
we only interpolate if the length of the lists match. If this changes
after spec discussions then the test will be updated.

Unify paths for constructing the style sheet list.

We used to have three different ways of constructing the DOM-visible
style sheet list (document.styleSheets), and one of them (the one
for documents) would mistakenly include adopted style sheets as part
of the list. This meant that document.styleSheets could differ
depending on whether we had recently updated RuleSets or not.

Make every path call the existing fast path (the one that only
constructs this list, not RuleSets and such), fixing the problem.
Also, add a test.
