We're currently letting render context overrides (opacity, color
filters, blend mode, etc) spill down the descendent/mask content
tree.
This is not ideal, as mask content isolation breaks atomicity
assumptions for deferred overrides. Case in point: motion blur uses
SkBlendMode::kPlus to accumulate content "layers" - but since mask
content gets rendered into a separate layer, it fails to produce the
expected result.
The fix is to realize all context overrides on the top-level mask layer
(we already allocate this layer, so there's no reason to defer
downstream anyway).

- shift the revalidation phase from Scene::render() to Scene::animate()
- pass an optional inval controller to Scene::animate() and Animation::seek()
- hoist the showInval logic out of SkSG, into clients
This allows clients to track dirty regions and detect cases where no updates are needed.

Update MotionTileEffect to avoid rebuilding shaders redundantly,
at render time:
1) build all shaders at revalidation time
2) cache the layer content picture separately, and only rebuild when
the layer content changes
To support #2, add some SG helpers for querying subtree inval state.
With this change, we avoid all render time allocations.

Two issues:
1) Empirically (per AE's model), only solid layers transform the effect space.
All other layer types implement their effects ignoring the layer xform.
2) Due to the effect deferral mechanism in sksg, shader effects are
sometimes applied with a different transform than intended.
To address #1, tweak the layer builder logic to attach the effects
before/after the transform node, depending on the layer type.
For #2, track the CTM active when the shader effect is attached and undo
any intervening transformations via a local matrix when the shader is
actually applied to SkPaint.

- since the gradient type (linear/radial) is animatiable (?!),
update sksg::ShaderEffect to allow resetting the shader
- gradient ramp doesn't have an assigned/stable JSON effect type,
but the data is present; introduce a name-based effect lookup method
(used as a fallback when the type is not recognized)

* introduce a new Shader base class
* refactor gradients as Shader subclasses
* introduce ShaderPaint (to support current Gradient-as-paint use)
* introduce ShaderEffect (to support future Gradient-as-effect use)
Tangentially:
* rename SkSGPaintNode.h -> SkSGPaint.h
* consolidate sksg::Color into SkSGPaint.h

AE supports two text layout modes [1]:
* point text: text is laid out on an infinite line, starting at the given position,
and observing explicit line breaks only; in this case the text baseline is at the
given position.
* paragraph (box) text: text is laid out within the given box, using line breaks to
fit.
This CL implements the latter mode, in addition to the already supported point mode:
- parse & plumb the text box info
- update the text adapter logic to use SkShaper's width-constrained shaping mode
- tangentially, fix sksg::TextBlob's bounds computation

Introduce sksg::BlendModeEffect and use to wrap Skottie layers based on
their "bm" property.
Depending on the presence of non-trivial layer blend modes and the nature
of the destination buffer (fully transparent vs. unknown/pre-filled), we
may now need to render animation frames into a separate layer for correct
compositing.
Track the presence of non-trivial layer blend modes such that we only incur
this extra layer overhead when needed. Also allow clients to pass a "drawing
to fully transparent buffer" hint such that we can avoid the extra layer even
when blend modes are present.
