This removes all of the fixed-function particle affector classes.
Instead, each particle effect just has two SkSL snippets, one for
spawn logic, and one for update logic. Each one gets an inout copy
of the particle struct. Ultimately, this makes the effects much
simpler and smaller, while also being far more flexible (you can
do whatever you want with any values you want). Finally, because
the interpreter is vectorized and a particular effect's scripts
are usually tuned to the specific behaviors desired, it's faster
on basically every effect I compared.
I re-created all of the old effects in the new system. Many just
use pure SkSL (no curves or anything). Some of the old curve and
path/text stuff was very handy, though - so those are now exposed
as external values in the interpreter. Basically, an effect can
have any number of named "bindings" that are a callable thing.
This can be a path, text (shortcut for making fancy paths), curve,
or color curve. The path ones return a float4 with position and
normal, the curves return one or four floats.
... and this transposes all of the particle data storage into
SoA form, so that it can use the much faster interpreter entry
point.

- 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.

When in GL backend, adds a "Shaders" section to the debug menu.
"Load" scrapes all of the vertex and fragment shaders being used,
then displays them. They can be edited, and "Save" pushes the
results.
Note: It is trivial to trigger an assert by saving a shader that
doesn't compile. I'd like to make the program builder more robust
in a follow-up CL, to fall back to the "real" SkSL, not draw, or
something along those lines.

The two existing external users of SkPaintFilterCanvas always end up
making a copy of the paint when the canvas is in use. As a result, the
extra overhead of doing COW is being wasted. In general, it seems easier
for users to optimize by simply not using the filter canvas when it
won't be making any changes. Also, no users are using the 'Type'.
After users are updated to this new API, the old onFilter can be
removed.

* 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
