Implements a simple first pass for a path renderer that uses the
classic Red Book "stencil then cover" method, and linearizes curves
with GPU tessellation shaders.
The new path renderer is disabled by default, and can only be enabled
in the viewer UI or by passing the "--pr gtess" flag.

There was never a need to distinguish between "all" and "default".
We can just use kDefalut everywhere. And as we add new path renderers,
we can exclude them from kDefault until they are ready to ship.

Adds a new structure to describe the inputs, including type,
shape, name, etc. This removes any references to the type
variables in the compiler's context, and centralizes the
logic for parsing those type variables.
Also normalizes the rules for what types are supported.
(This was inconsistent among the various functions before).
Now:
- bool and int must be 'in'
- float may be 'in' or 'uniform'
- float[2-4] and matrices must be 'uniform'
Includes a new Slide that allows for interactive editing
of a runtime shader.

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.

animation like scrolling or flying and resizing text the animation
suffers. Allow the user to disable the baseline snapping.
