Use `tcx.param_env(def_id)` instead of `ty::ParamEnv::empty()`.

`ParamEnv` tracks details about the set of `where` clauses.  Using
`tcx.param_env(def_id)` seems more correct than using
`ty::ParamEnv::empty()` and assumming that we are dealing with a
non-generic item.

Note that in the currently supported scenarios the old and new code
should be equivalent - we expect no `where` clauses in the supported
scenarios.  In particular,
`test_format_item_lifetime_generic_fn_with_where_clause` verifies that
there `where` clauses are not supported for lifetime-generic functions.
