Several SVG constructs reference other elements based on their ID (e.g.
<use>). This can yield arbitrary reference chains and cycles.
Since all ID-based lookups are funneled through
SkSVGRenderContext::findNodeById(), a straightforward method to break
cycles is to temporarily clear the id->node association following a
lookup -- where "temporarily" refers to the local execution scope.
This approach works for all recursive traversals, as scopes are
nested/released in a natural manner.
- introduce a scoped node reference wrapper (BorrowedNode), which
clears the id mapping for its lifetime and restores it upon
destruction
- update findNodeById() return BorrowedNode values
- update call sites as needed

Current strategy: everything from the top
Things to look at first are the manual changes:
- added tools/rewrite_includes.py
- removed -Idirectives from BUILD.gn
- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout
so that #include "include/config/SkUserConfig.h" always
gets the header we want.

- Replace sk_memory_order with std::memory_order.
- Remove SkAtomic<T>.
SkPath was the only user of SkAtomic<T>, for its fConvexity and
fFirstDirection fields. I've replaced them with std::atomic types, and
funneled access to them through methods that enforce the relaxed memory
order like SkAtomic<T> did.
For fConvexity, we can use the exisiting setConvexity() and
getConvexityOrUnknown() methods, adding a private const setConvexity()
to mutate convexity from const methods. For fFirstDirection I've added
private setFirstDirection() and getFirstDirection() methods.
Removing SkAtomic<T> means SkAtomics.h no longer needs SkNoncopyable.h.
I've had to update a bunch of other headers that were depending on
transitive inclusion.

The Skia SVG DOM is not a user agent, so link semantics are not
particularly interesting. But since <a> can wrap actual content, it is
important to not drop it on the floor.
The simplest thing to do is turn it into a <g> node and run with it.

ClipPaths can be clipped too, e.g.:
<clipPath id="clip1" clip-path="url(#clip2)">...</clipPath>
Since we're not really drawing clips but resolving their geometry,
asPath() needs to take composed clipping into account (and intersect as
needed).

There's a bit of friction with this attribute, because per spec it is
an inherited presentation attribute, but in Skia it is part of the
actual SkPath state.
So we must add some plumbing to SkSVGShape & friends to allow overriding
the fill type at render-time.
