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.

Treat SVG documents in / as replaced elements

SVG documents loaded inside or elements were being
treated as regular iframe content rather than as replaced elements. As a
result, CSS properties like object-fit and object-position were being
ignored.

This CL modifies LayoutEmbeddedContent::ReplacedContentRectFrom() to
detect SVG documents and apply the replaced element logic of their base
class, making SVG content behave like images.

The test external/wpt/fullscreen/rendering/backdrop-object.html started
failing as a result of this CL, because the default value of
object-position is not what the reference assumed. Since this
functionality is outside the focus of that test, the solution was to
explicitly align object-position with the expectations of the reference.

Fix incorrect usage of percentage unit in tab-size test

This CL changes the incorrect use of word-spacing: 100% to 1ch in
the tab-size-spacing-003.html test.

In CSS Text Level 4, percentage values for word-spacing are defined to
resolve against the computed font-size of the element, not the advance
width of the space character. Meanwhile, tab-size is defined as a
multiple of the advance width of U+0020.

As a result, comparing tab-size alignment to spacing derived from
word-spacing: 100% mixes unrelated units and leads to an invalid test
condition.

This patch replaces the percentage value with 1ch to preserve the test
intent while ensuring spec compliance.
