As requested during the review of https://github.com/servo/servo/pull/42991. These functions are currently called `{to, from}_layout_js` or sometimes `get_jsmanaged` - this change unifies them as `{to, from}_layout_dom` for clarity. Testing: Covered by existing tests Signed-off-by: Simon Wülker <simon.wuelker@arcor.de>
