This defines a macro to cut down on boiler plate for generating sksl test resources.

"""Creates a rule to compile the given sksl inputs
This macro creates a py_binary rule to invoke the //gn:compile_sksl_tests.py script and a
helper genrule which creates the list of all file names that should be processed by that
python script.
The generated py_binary rule is called compute_${name} and can be run via `bazel run`.
Args:
name: A string used to uniquely identify the generated compile and list rule.
lang: A string passed into the compile_sksl_tests.py script.
inputs: A filegroup label containing all the input files to be processed.
settings: A string passed into the compile_sksl_tests.py script.
