Rule based toolchains should expand `args` with `data`

I wrote a args rule like this:

```bzl
cc_args(
name = "asan_compile_args",
actions = ["@rules_cc//cc/toolchains/actions:compile_actions"],
args = [
"-fno-sanitize-recover=all",
"-fsanitize=address",
"-fsanitize-ignorelist=$(location //bazel/internal:asan-suppressions.txt)",
],
data = [
"//bazel/internal:asan-suppressions.txt",
],
)
```

Which I think we should be able to support
