The default colorspace for filter effects is linear RGB, as specified in
https://www.w3.org/TR/SVG11/painting.html#ColorInterpolationProperties.
Currently we perform all filtering in the destination colorspace. This
CL adds the new presentation attribute with the default setting
(according to the spec) of linear RGB.
This CL does not actually implement any colorspace transformations for
filters.

- introduce SkSVGTextPath and update the text render logic to
instantiate new SkSVGTextContexts in onRenderText() overrides
instead of renderText() root -- this is to observe spec semantics
[1] requiring <text> and <textPath> to always start a new chunk,
regardless of their relative nesting.
- expand SkSVGTextContext to also store PathData when used in the
scope of a textPath
- PathData caches SkContourMeasures, for path position lookup
- update flushChunk() to apply path glyph adjustments [2]:
* the horizontal glyph position (including relative offset dx),
adjusted for the glyph center yields a path offset
* if the offset is outside the path range, the glyph is skipped
* otherwise the position is determined based on the path matrix
at the computed offset
- to support the logic above, the chunk starting position is no
longer used as a global blob offset but instead is folded into
individual glyph RSXforms (and the blob always draws at {0,0})

Spec: https://www.w3.org/TR/SVG11/filters.html#FilterPrimitiveSubRegion
The filter primitive subregion restricts the output of a specific <fe*>
node in a filter DAG. By default it's equal to the union of subregions
of all input filters, or the filter region if no inputs exist. If
x/y/w/h are specified on the <fe*> node, those are used to bound the
primitive subregion instead.
In this CL:
- Implement the computation of the primitive subregion in
SkSVGFe::resolveFilterSubregion
- Add primitiveUnits to filter context
- Change result registration (by string ID) in filter context to include
the primitive subregion of that result. This is needed because filters
referencing previous results need access to those primitive subregions
to compute the union.

Previously ExternalValues were flexible, and could be used as raw values
(with the ability to chain access via dot notation), or they could be
callable. The only non-test use-case has been for functions (in
particles) for a long time. With the push towards SkVM, limiting
ourselves to this interface simplifies things: external functions are
basically custom intrinsics (and with the SkVM backend, they'll just get
access to the builder, and be able to do any math, as well as
loads/stores, etc).
By narrowing the feature set, we can rename everything to reflect that,
and it's overall clearer (the SkSL types now mirror FunctionReference
and FunctionCall directly, particularly in how they're handled by the
CFG and inliner).

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

- introduce ShapeBuffer to store both utf8 text and position
adjustments for shaping (replaces prev 'filtered' array).
- position adjustments are cumulative (relative adjustments affect
all following characters)
- utf8 encoding is variable length; for simplicity, ensure that the
pos adjustment array and the utf8 array are always the same size by
repeating the pos adjustment times number of utf8 bytes
- introduce a temporary buffer for retrieving utf8 cluster information
from SkShaper
- post-shaping, use the utf8 cluster info to map back to character
