This bug will presumably fix this interop-2023 test:

In layout, we build a default path("m 0 0") for now. We will implement
it later.

Besides, we don't support compositor animations for url().

Attachment: Bug 1598158 - Resolve URL to SVG shape elements.

Also, rename mIsClosedIntervals as mIsClosedLoop (and some other
similar renamings) to match the spec words.

Note: I also update offset-path-url-001.html because it seems its ref
html is incorrect per the current spec. We are using its <coord-box> (i.e.
the reference box of its containing block) as the viewport and user coordinate
system, so its offset-starting-position should be independent from its
current position from CSS reflow. The SVG shape element always provide the
offset starting position.

So I tweak offset-path-url-001.html a little bit to make it passed for all
browsers, and add some other tests to cover the case I mention above and
other cases.
