Allow `toolchain_info` to bind arguments to the binary.

py_binary(
    name = "xxx",
)

toolchain_info(
    name = "info",
    target = ":xxx",
    args = ["--abc", "def"],
)

bazelisk run -- :info --hey would run xxx --abc def --hey

We would need a POSIX Shell and Batch wrapper script to replace the current symlink.

Argument escaping is challenging here.
