layout: Use ServoLayoutNode directly instead of a generic impl (#36876)

This makes it so that layout is no longer generic on the node type,
depending directly on `script`'s `ServoLayoutNode`. In addition to
greatly simplifying layout, this is necessary because incremental layout
needs to be able to create pseudo-element styles without having a handle
on the original `impl LayoutNode`. We feel this is a reasonable
tradeoff.

Testing: No functional changes, so covered by existing WPT tests.
