1. Add arguments parameter to RunEnvironmentInfo …

   Executable Starlark rules can use the new `arguments` parameter on
   `RunEnvironmentInfo` to specify the arguments that Bazel should pass
   on the command line with `test` or `run`.
   
   If set to a non-`None` value, this parameter overrides the value of
   the `args` attribute that is implicitly defined for all rules. This
   allows Starlark rules to implement their own version of this attribute
   which isn't bound to its proprietary processing (data label expansion
   and tokenization).
   
   Along the way, this commit adds test coverage and documentation for the
   interplay between `RunEnvironmentInfo`'s `environment` and `--test_env`.
   
   The value of the `arguments` field of `RunEnvironmentInfo` is
   intentionally not exposed to Starlark yet: It is not clear how these
   arguments should be represented and whether rules relying on the magic
   `args` attribute should also provide this field.
   
   RELNOTES: Executable starlark rules can use the `arguments` parameter of
   `RunEnvironmentInfo` to specify their command-line arguments with `bazel
   run` and `bazel test`.
