Move methods from `Map` to `TyCtxt`, part 4. 

Continuing the work from #137350.

Removes the unused methods: `expect_variant`, `expect_field`,
`expect_foreign_item`.

Every method gains a `hir_` prefix.

@ -139,12 +139,12 @@ defined in the map. By matching on this, you can find out what sort of
node the `HirId` referred to and also get a pointer to the data
itself. Often, you know what sort of node `n` is – e.g. if you know
that `n` must be some HIR expression, you can do
[`tcx.hir().expect_expr(n)`][expect_expr], which will extract and return the
[`tcx.hir_expect_expr(n)`][expect_expr], which will extract and return the
[`&hir::Expr`][Expr], panicking if `n` is not in fact an expression.
