This change adds another layer of complexity and control to
the particle system. There are now two code chunks: the old
code that's run per-particle, and new code that's run for
the effect itself. This allows for effect lifetime to be set
by the script (eg, randomly), as well as the emission rate.
Rate can vary over time (see pulse.json), and particles can
be emitted in bursts by setting the effect's burst field
(see fireworks.json).
Additionally, the effect has its own frame of reference and
color, which becomes the default state for newly emitted
particles. This allows synchronizing state across particles
in various interesting ways (see color in fireworks.json).

The client can do a test run of their application with
a persistent cache set to SkSL mode. They store the key
and data blobs that are produced.
Ship those blobs with the application. At startup, call
GrContext::precompileShader for each key/data pair. This
compiles the shaders, and stores the GL program ID, plus
a small amount of metadata in our runtime program cache.
Caveats:
* Currently only implemented for the GL backend. Other
backends will require more metadata to do any useful
amount of work. Metal may need a more drastic workflow
change, involving offline compilation of the shaders.
* Currently only implemented for cached SkSL (not GLSL
or program binaries). Supporting other formats again
requires more metadata, and the cached shaders become
increasingly specialized to GPU and driver versions.
* Reusing the cached SkSL on different hardware is not
supported. Many driver workarounds are implemented in
the SkSL -> GLSL transformation, but some are higher
level. Limiting device variance by artificially hiding
extensions may help, but there are no guarantees.
* The 'gltestprecompile' DM config exercises this code
similarly to 'gltestpersistentcache', ensuring that
results are visually identical when precompiling, and
that no cache misses occur after precompiling.

Skia has traditionally snapped horizontal and vertical baslines to
pixels as a kind of baseline hinting. This is a feature which cannot
reliably be implemented from the outside and tends to make static text
better looking by ensuring the baselines are consistent. However, with
animation like scrolling or flying and resizing text the animation
suffers. Allow the user to disable the baseline snapping.

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.
