Implement drop and inner shadow styles using explicit image filters.
Remove existing style support from DropShadowEffect.cpp, as it now
has a new cozy place with its inner sibling.
Supported properties:
- color
- opacity
- angle
- distance
- size (sigma)

Since we can't use mask filters on layer paints any longer, refactor the
existing wipe effects to use explicit shader masking:
- remove SkSG::MaskFilterEffect - it no longer works
- replace with SkSG::MaskShaderEffect
- for atomic draws, apply the shader to the draw paint as
SkShader::Blend(kSrcIn, mask_shader)
- for isolated content, apply the mask as an extra pass
drawPaint(kDstIn, mask_shader) before restoring the layer
- refactor VenetianBlindsEffect, LinearWipeEffect and RadialWipeEffect
to use mask shaders
- additionally, refactor the RadialWipeEffect gradient to avoid using
a local shader matrix (does not compose correctly within the new
framework)
Everyone clear... do not touch the patient... BZZZT!

Add SkMaskFilter scene graph nodes and implement AE's linear wipe effect
as a gradient shader mask filter.

Current strategy: everything from the top
Things to look at first are the manual changes:
- added tools/rewrite_includes.py
- removed -Idirectives from BUILD.gn
- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout
so that #include "include/config/SkUserConfig.h" always
gets the header we want.

Implement gradient ramp using SG shader effects.
A couple of quirks:
- 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)

Currently, gradients are PaintNode subclasses - which limits their
applicability to leaf DAG nodes.
In order to support generalized gradient/shader effects:
* 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

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.

Introduce RenderNode::nodeAt(const SkPoint&) as the entry point for the hit-testing API.
This is backed by a onNodeAt() virtual, which gets dispatched throughout the render DAG,
and normally stops at the first leaf Draw node in encounters.
To support the implementation, introduce a GeometryNode::contains(const SkPoint&) API.
This is backed by a onContains() virtual, overridden in each concrete geometry class.
Expose nodeAt() on sksg::Scene, and add some basic unit tests.
