https://www.w3.org/TR/SVG11/filters.html#feSpecularLightingElement
Because a fair amount of functionality will be shared between
feSpecularLighting and feDiffuseLighting, this CL adds an intermediate
SkSVGFeLighting base class for common code.
The only light source type implemented in this CL is fePointLight, which
exercised by the filters-light-03 W3C test.

The three classes represent light source elements that will eventually
be used for feSpecularLighting and feDiffuseLighting. Currently they are
unused.
Also added the (currently unused) lighting-color presentation attribute.

Introduce SkSVGMask and plumb related attributes.
Also consolidate the clip/mask/filter property types - they all support
the same values: <funciri>|none|inherit.

This filter implementation should be complete, but note we are still
not quite passing the W3C filters-gauss-* tests because our filters
currently operate in sRGB and not linear RGB (which is quite noticable
in some of the blur tests).

- Plumbing to store filter results by id and resolve them as inputs
when referenced
- Added implementation of feComposite filter
- Added call to resolve input in feColorMatrix
- Bugfix to SkSVGFilterType operator==
The tests filters-color-01-b and filters-composite-03-b should now be
passing.

Supporting this filter will also allow us to start implementing and
testing the filter result DAG via the filters-color-01-b test. That test
is one of the simplest that involves filter result storage, so it's a
good candidate to start with.

This was the simplest one to start with. I need to add support for the
"filter effect subregion" in order to handle tile stitching property,
so this isn't quite complete. But I believe this is enough for the
basic filters-turb-01-f test to pass, which gives us a baseline for
further filter work.
Summary of changes:
- Added attribute type and parsing for SVG integer datatype
- Added new node class for feTurbulence
- Added several new properties and parsing for feTurbulence

Added:
- SkSVGFilter: This corresponds to a <filter> element. Also added some
of the attributes of this element.
- SkSVGFe: This will be the base class of all <fe*> elements.
- SkSVGFilterContext: This will hold the contextual mapping of string id

Move the SVG rendering code to modules/svg, and componentize.
Also split into include/src/utils.
As external clients still reference the old header locations,
introduce temporary forwarding headers to facilitate the migration.
