The table element should be repainted whenever the caption-side is changed

Changing the caption-side property of the caption element triggers a
data structure update in the table element. The value of TableGridRect
is correctly calculated, but since the table element was not marked for
repaint, the DisplayItem used cached items. In this case, we mark the
table element for repaint. Updates to the data structure trigger the
cell repainting, while a full repaint of the table element has minimal
impact on performance.

Fix crash in flex gap suppression code

This CL addresses a crash introduced in crrev.com/c/6657779, caused by
a CHECK failure in the flex gap suppression logic. The CHECK enforces
that the row gap should always be greater than or equal to the
available space in a given fragmentainer. While the assumption itself
is valid, the method used to compute the available space was flawed.

Previously, the available space was derived from intrinsic_block_size_,
which represents the tallest item in the row. However, in cases where
the actual block size of a row exceeds the intrinsic block size, this
calculation becomes inaccurate, leading to the CHECK failure.

This change corrects the calculation by using the previous row’s
block end instead of relying solely on the intrinsic block size. This
ensures a more accurate representation of the available space and
prevents the crash.

Check properly if a container has perspective.

Don't just check the perspective property, but also if it applies. It
doesn't apply to non-atomic inlines, for instance.

[SVG] Add CSS width and height support for element

This CL introduces support for applying width and height as CSS
properties to SVG element. The primary change is that the
viewport size for a element referencing a is
now determined by the computed width and height of the element,
rather than the attributes or styles of the or another
element.

Key Behavior Changes:

1. Enables width and height as presentation attributes on .
2. Viewport resolution prioritizes 's width and height over
   's or another element.
