[CodeHealth] Remove DictionaryValue in components/permissions

This converts usage of base::DictionaryValue to base::Value in
components/permissions. Most of the conversion was going from
unique_ptr<base::DictionaryValue> to unique_ptr<base::Value>. While we
are moving away from heap-allocated base::Values, these particular
values are std::moved to other APIs expecting unique_ptr<base::Value>.

Usage of base::ListValue was also converted to base::Value.
