This CL makes it explicit that the unit tests always get a direct context.
It is mainly a mechanical CL.

This is needed for the inline dither effect to use device coordinates
instead of local coords for dithering.
The builtin is not "in float4" because that trips up the runtime effect
assertions about what types of in variables are allowed.

If you used 'in float foo' in a runtime effect it would always have the
value cast to an int. I don't think we saw this in .fp files because
the cpp generation handled those values directly (if I remember correctly)
Just uses a union of float and int, differentiated by fKind, so that it
compiles in standalone mode (vs. using SkFloat2Bits, etc.).
Also updated to add a unit test.

Utility class for getting named access to uniforms and children of an
SkRuntimeEffect (also functions as an example of using the
SkRuntimeEffect public API).
Moved several internal SkRuntimeEffect functions to private, and added
findInput/findChild helpers.

Previously, the CPU backend would catch this later (ByteCodeGenerator),
and the GPU backend would assert in expandFormatArgs (out-of-range
function index).

Added this as an option to GrSaturateProcessor (also renamed it to
be more generic and end with FragmentProcessor).
Added a tweak to the unit test to check the new behavior.
(Raster was already doing the clamp).

We were never calling specialize() to bake in the values of ins,
so do that. Add uniformSize() to get the size of just the uniform
values. (The interpreter asserts that the size of the uniforms
being passed in matches the expected size from the ByteCode,
so these need to match up).
Added a unit test that uses both 'in' and 'uniform'.

- Change SkRuntimeEffect::Make so *it* can fail, and returns
[Effect, ErrorText].
- Initial tests just test for expected failure conditions.
Next steps are to add tests for effects that should work,
and to validate results on CPU and GPU.
