Handle layer clients in LayoutSVGResourceContainer::registerResource

When registering pending clients on a newly discovered (filter) resource,
make sure to invalidate via the DeprectatedPaintLayer if the client has
one, or the client won't be updated properly.
Make SVGResourcesCache::clientStyleChanged handle non-SVG elements.

This was exposed by scheduler changes that caused flaky behavior in
LayoutTests/css3/filters/effect-reference-rename.html, where the
script:

  document.getElementById("NotMyFilter").id = "MyFilter";

would normally execute before the call to registerResource() that added
MyFilter. With the scheduler these could happen in the opposite order
and trigger the "layoutObject->node()->isSVGElement()" assert.
