typing: add type hints to argument checking functions in cmdutil

These might be surprising, since they can take strings instead of bytes.  The
way `AnyStr` works is that it must be all bytes or all str for any given
invocation.

The wildcard here will be the `opts` that get passed in- if the type is unknown
and defaults to `Any`, there's no enforcement that the dict key type matches the
additional args.  But a lot of uses should be using `**opts` from the command
method, which has a str key.  The uses of these methods in this module are now
typed because their internals force a specific type, and it can't just be
inferred from the caller.
