Remove the SVG tear off objects for SVGPathSeg, SVGPathSegList and SVGAnimatedPathSegList
https://bugs.webkit.org/show_bug.cgi?id=196085

Patch by Said Abou-Hallawa <sabouhallawa@apple.com> on 2019-03-27
Reviewed by Simon Fraser.

Source/WebCore:

The SVGPathSegList is similar to the other SVGLists, e.g. SVGNUmberList
and SVGPointList except in two things:

1. Its items can be different but they are derived from the same base
   class SVGPathSeg.

2. The SVGPathSeg items are only used for DOM. When drawing or animating
   we have to have an SVGPathByteStream and convert it to a Path. Converting
   an SVGPathByteStream to SVGPathSeg items and vice versa is expensive.
   Building a Path from an SVGPathByteStream is also expensive. So an extra
   care needs to be taken for when these conversions happen.

In addition to handling the SVGPathSeg items, SVGPathSegList will manage
the associated SVGPathByteStream and Path objects. SVGPathSegList will be
lazy in getting updated objects when a change happens. For example, when
the byte stream changes, SVGPathSegList will clear its items and nullify
the Path object. But it will not build any of them until they are explicitly
requested.

Like what was done for other SVG properties when removing their tear off
objects, a new accessor, a new animator and a new animation function will
be added for the SVGAnimatedPathSegList.

All the header files of the concrete classes of SVGPathSeg will be removed
because they are small structures which hold some data items and they provide
setters and getters for these items. Here is the new file structures and
their contents:

-- SVGPathSeg.h still has the class SVGPathSeg which is now a superclass
   of SVGProperty.

-- SVGPathSegValue.h will have the template class SVGPathSegValue which
   holds an std::tuple of packed arguments. It provides setters and getters
   for these arguments. SVGPathSegValue.h will also have specialized
   classed derived from SVGPathSegValue and hold different arguments.

-- SVGPathSegImpl.h will have the final concrete SVGPathSeg classes.

Note SVGPathSeg concrete classes do not need to have a reference to the
the context SVGPathElement. SVGPathSeg will be owned by its SVGPathSegList
which will be owned by the SVGAnimatedPathSegList which will be owned by
the SVGPathElement.
