[LBSE] Fix transform support for SVG <text> elements

https://bugs.webkit.org/show_bug.cgi?id=245508

Reviewed by Rob Buis.

RenderSVGBlock::referenceBoxRect() was missing (affecting RenderSVGText), thus the
refeferenceBoxRect() for a RenderSVGText renderer was computed according to CSS rules,
see RenderBox::referenceBoxRect(), and not according to the SVG rules, implemented in
RenderLayerModelObject::referenceBoxRect() -- fix that.

This also uncovered a LBSE specific isssue with SMIL <animateMotion> - they were
post- instead of pre-multiplied, fix that as well, while I'm at it.

Covered by numerous existing tests that now function properly in LBSE.
