layout: Add initial support for the ::marker pseudo-element (#36317)

This change adds support for the `::marker` pseudo-element and ensure
that
markers are cached into the box tree. This is only initial support,
there are a few
things missing such as animations, transitions, and support the
`content` CSS
property.

Testing: There are WPT tests for this change.
