  [LBSE] Allow to query supplementalTransform() without creation
https://bugs.webkit.org/show_bug.cgi?id=247670

Reviewed by Rob Buis.

There is no way to check for the presence of SMIL supplementalTransform() instances,
since calling that method implicitly creates it. Split it up into another
ensureSupplementalTransform() method, that forces creation and another supplementalTransform()
method that simply returns the object, if present.

Covered by existing tests.
