John Stiles 2955c26908 Add new SampleBlender callback to SkVMCodeGenerator.
This CL doesn't actually allow the callbacks to be invoked from SkSL
yet, but the callbacks now exist and are now threaded through the
various callsites which will need them.

We fuzz Skia using oss-fuzz, which in turn uses fuzzing engines such as libfuzzer, afl-fuzz, hong-fuzz and others.

We define a fuzzer to be a targeted bit of code that takes a randomized input and executes code in a specific area. For example, we have a codec fuzzer which takes a mutated png/jpeg or similar file and attempts to turn it into an SkImage. We also have a canvas fuzzer which takes in a random set of bytes and turns them into calls on SkCanvas.

See [../site/dev/testing/fuzz.md] for more information on building and running fuzzers.
