Fix nested traversals

Multiple crashes were occurring due to inconsistencies between option
traversals. OptionList was not considering nested s to be
associated with the select. However, HTMLOptionElement::InsertedInto and
HTMLOptionElement::OwnerSelectElement were considering nested s
to be associated with selects.

This patch makes the traversals consistent by disallowing nested

s from creating associations with elements.

View transition layered capture: determine geometry based on box model

Instead of capturing the border offset, we capture the following
layout sizes to determine sizing, in addition to the border box:

• padding box

• content box

• The box-sizing property

• In layered capture mode, we use the content box size as the
  reference box for positioning the snapshot, so that padding take
  effect.

• The ::view-transition-image-pair pseudo-element now has
  position:relative so that it gets affected by padding. It has the
  content box size.

• The width/height of the group is determined by the box-sizing
  property, and it receives the computed padding.

[@scope] Calculate full nesting context in ParseRuleForInsert

We ignored @scope entirely in ParseRuleForInsert, causing rules inserted
into @scope rules to parse incorrectly.

'CalculateNestingContext' is a separate function, because the same
functionality will be needed in other places (setSelectorText).

layout: Fix trailing collapsible space handling with

• Trailing collapsible space should not be handled in ruby-base lines
  because such lines are contained by another line.
  This CL introduces LineBreaker:: disable_trailing_whitespace_collapsing_.

• ComputeTrailingCollapsibleSpace() should iterate inside ruby columns
  recursively.

• RemoveTrailingCollapsibleSpace() and TrailingCollapsibleSpaceWidth()
  should compute ruby column widths correctly.

• ruby-intra-level-whitespace-001.html passed accidentally. It requires

[line-clamp] [text-box-trim] Trim the last line before clamp inside nested blocks

When text-box-trim: trim-end is used together with line-clamp, it
should trim the block-end leading of the last line before clamp, the
one with the ellipsis. This worked when that last line before clamp is
directly contained by the line-clamp container, but it doesn't when it
is inside a nested block element.

The reason for this is that, although for InlineNodes,
ConstraintSpace::ShouldTextBoxTrimNodeEnd is always set if the
parent BlockNode is as well; for BlockNodes, that flag is only set
for nodes that are the last in-flow child node of its parent.

This means that, for line-clamp, there is no flag to tell a child
BlockNode that it is fine to trim if there's a clamp point inside
it, even if it wouldn't be fine to trim in its last formatted line.
This patch therefore adds a ShouldTextBoxTrimInsideWhenLineClamp
field to ConstraintSpace to indicate this.

[line-clamp] Fix DCHECK failure with hidden block-in-inlines

When painting a hidden-from-paint block-in-inline (which can happen if
the block-in-inline is after the clamp point in a line-clamp
container), there was a DCHECK failure since
BoxFragmentPainter::PaintBoxItem was not expected to be called on
hidden for paint items. This is because, in all other cases, this call
is skipped if the item is hidden, but that was not the case for block
in inlines. This patch fixes this by adding a condition before the
call in
BoxFragmentPainter::PaintBoxDecorationBackgroundForBlockInInline.
