Implement support for text 'rotate' attribute:
https://www.w3.org/TR/SVG11/text.html#TSpanElementRotateAttribute.
Unlike other character-positioning attributes (x/y/dx/dy), rotate
- is not cumulative
- only applies to its respective node scope (does not affect other
fragments in the current chunk)
- has different padding semantics: if there are fewer rotate
values than characters, the remaining characters use the last
specified value from the closest ancestor
To the last point, we now have to discriminate three states:
- unspecified (default -> 0)
- explicit value for the given character index
- implicit value (last value in the closest ancestor)
Local implicit values override implicit ancestor values -- but not
explicit ancestor values.
High level changes:
- plumb 'rotate' attribute
- expand per-character position info (ShapeBuffer) to include rotation
- expand per-glyph position info (RunRec) to include rotation
- expand PosAttrs to include rotation and add specific inheritance
rules (see above)
- pass computed rotation values to RSX blob buffers

These are somewhat the first presentation attributes of their kind,
in that they are non-inherited but also not applied via canvas layers.
Implementation-wise the main difference is that these attributes are
not propagated through the fInherited field of the render context's
presentation attribute list.

This generic parsing will allow us to later remove kInherit and
"inherit" parsing from all other specific SVG types.
Also convert "filter" presentation attribute to new-style parsing
for compatibility with the setter.

- Added SkSVGIRI type -- we need explicit types now to be able to
dispatch via the templated parse function
- Converted several attribute parse functions to templated version

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.

- remove the custom-func SkSVGAttributeParser::parse version and always
dispatch via SkSVGAttributeParser::parse<T>(T*) - this should
avoid adding any other parse helper declarations in the future
- relocate the turbulence parse helpers to SkSVGAttributeParser (while
keeping the definition in SkSVGFETurbulence.cpp)
- update ParseResult initialization to use move semantics

One significant source of boilerplate in the SVG frontend is the
plumbing to ensure type safety all the way down from the XML layer to
the SkSVGNode layer. This is mostly an artifact of the top-down parsing
approach currently used by the SkDOM -> SkSVGDom building process.
One way to help remove some boilerplate is to perform attribute parsing
bottom-up, where each SVG node knows how to parse and populate its own
attribute values from a string-valued KV pair.
Additionally, bottom-up parsing allows us to support the case of the
same SVG attribute name having different meanings on different nodes
(e.g. the "type" attribute has different meaning on <feTurbulence>
versus <feColorMatrix>).
This CL adds some initial work to start us down that road, and ports the
attributes previously added for <feTurbulence> to use the new code path.

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

Also split into include/src/utils.
As external clients still reference the old header locations,
introduce temporary forwarding headers to facilitate the migration.
