base: drop redundant Typeable derivings
Thanks to #9858 `Typeable` doesn't need to be explicitly derived anymore. This also makes `AutoDeriveTypeable` redundant, as well as some imports of `Typeable` (removal of whose may be beneficial to #9707). This commit removes several such now redundant use-sites in `base`. Reviewed By: austin, ekmett Differential Revision: https://phabricator.haskell.org/D712
