rustdoc: Support argument files

Factors out the `rustc_driver` logic that handles argument files so that rustdoc supports them as well, e.g.:

    rustdoc `@argfile`

This is needed to be able to generate docs for projects that already use argument files when compiling them, e.g. projects that pass a huge number of `--cfg` arguments.

The feature was stabilized for `rustc` in #66172.
