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`.
