The previous behavior leaked Skia-internal concepts into public SkSL.
Users coming from GLSL will expect that bindable/sampleable objects are
uniform (just like texture2D). This keeps the old support around (and
tested), but updates all of our examples to use 'uniform'.

There is no more 'inout half4 color'. Effects return their output color.
If an effect wants the input color, it must use the (already existing)
approach of sampling a nullptr input shader.
The change is guarded for Chromium (so we can update their runtime color
filters in skia_renderer.cc).
For the GPU backend, FPs can now override usesExplicitReturn to indicate
that their emitCode will generate a return statement. If that's true,
then writeProcessorFunction doesn't inject the automatic return of the
output color, and emitFragProc will *always* wrap that FP in a helper
function, even as a top-level FP. GrSkSLFP opts in to this behavior, so
that the user-supplied return becomes the actual return in the FP's
emitCode.
Adapting the skvm code to this wasn't too bad: It looks fragile (what
happens if there are multiple returns?), but that's not really possible
today, without varying control flow.

Runtime effects previously allowed two kinds of global input variables:
'in' variables could be bool, int, or float. 'uniform' could be float,
vector, or matrix. Uniform variables worked like you'd expect, but 'in'
variables were baked into the program statically. There was a large
amount of machinery to make this work, and it meant that 'in' variables
needed to have values before we could make decisions about program
caching, and before we could catch some errors. It was also essentially
syntactic sugar over the client just inserting the value into their SkSL
as a string. Finally: No one was using the feature.
To simplify the mental model, and make the API much more predictable,
this CL removes 'in' variables entirely. We no longer need to
"specialize" runtime effect programs, which means we can catch more
errors up front (those not detected until optimization). All of the API
that referred to "inputs" (the previous term that unified 'in' and
'uniform') now just refers to "uniforms".

The majority of existing call sites were automatically updated using

e.g. CppCodeGen.
This check is a bit lenient, and in particular will not flag cases like
`std::unique_ptr<Base>(new Derived())` which is still pretty common
throughout our codebase. This CL does not attempt to replace all the
cases that ClangTidy does not flag.

any other code had been emitted, so if the expression referred to

At this point, every created instance of GrCoordTransform is an identity
so can be removed. Adding it manually using addCoordTransforms() is no
different than relying on the (current) implicitly returned coord
transform if the FP calls setUsesSampleCoordsDirectly().
Removing the addCoordTransform() lets us enforce that this remains the
case and this CL also deletes all of those members that were previously
used to provide access to the sample coordinates.
As part of this, GrFragmentProcessor.h and many other files no longer
need to include GrCoordTransform.h. This exposed a surprising popularity on
SkMatrixPriv.h so I updated those files to include that header directly.
Technically, a .fp file can still have an @coordTransform section and
the sksl generator will try and call addCoordTransform, which will then
fail to build. A follow up CL removes that support in .fp generation.

This removes the kMixed type of SkSL::SampleMatrix. All analysis of FP
sampling due to parent-child relationships is tracked in flags on
GrFragmentProcessor now.
The sample strategy is tracked as follows:
- An FP marks itself as using the local coordinate builtin directly (automatically done for .fp code based on reference to sk_TransformedCoords2D[0]).
- This state propagates up the parent towards the root, marking FPs as using coordinates indirectly. We stop the propagation when we hit a parent FP that explicitly samples the child because it becomes the source of the child's coordinates.
- If that parent references its local coordinates directly, that kicks off its own upwards propagation.
- Being sampled explicitly propagates down to all children, and effectively disables vertex-shader evaluation of transforms.
- A variable matrix automatically marks this flag as well, since it's essentially a shortcut to (matrix expression) * coords.
- The matrix type also propagates down, but right now that's only for whether or not there's perspective.
- This doesn't affect FS coord evaluation since each FP applies its action independently.
- But for VS-promoted transforms, the child's varying may inherit perspective (or other more general matrix types) from the parent and switch from a float2 to a float3.
- A SampleMatrix no longer tracks a base or owner, GrFragmentProcessor exposes its parent FP. An FP's sample matrix is always owned by its immediate parent.
- This means that you can have a hierarchy from root to leaf like: [uniform, none, none, uses local coords], and that leaf will have a SampleMatrix of kNone type. However, because of parent tracking, the coordinate generation can walk up to the root and detect the proper transform expression it needs to produce, and automatically de-duplicate across children.
Currently, all FP's that are explicitly sampled have a signature of (color, float2 coord). FP's that don't use local coords, or whose coords are promoted to a varying have a signature of (color).
- In this case, the shader builder either updates args.fLocalCoords to point to the varying directly, or adds a float2 local to the function body that includes the perspective divide.
GrFragmentProcessor automatically pretends it has an identity coord transform if the FP is marked as referencing the local coord builtin. This allows these FPs to still be processed as part of GrGLSLGeometryProcessor::collectTransforms, but removes the need for FP implementations to declare an identity GrCoordTransform.
- To test this theory, GrTextureEffect and GrSkSLFP no longer have coord transforms explicitly.
- Later CLs can trivially remove them from a lot of the other effects.
- The coord generation should not change because it detects in both cases that the coord transform matrices were identity.
GrGLSLGeometryProcessor's collectTransforms and emitTransformCode has been completely overhauled to recurse up an FP's parent pointers and collect the expressions that affect the result. It de-duplicates expressions between siblings, and is able to produce a single varying for the base local coord (either when there are no intervening transforms, or the root FP needs an explicit coordinate to start off with).
This also adds the fp_sample_chaining GM from Brian, with a few more configurations to fill out the cells.
