E0318 needs to be updated to new format

[sophiajt]

From: src/test/compile-fail/typeck-default-trait-impl-outside-crate.rs

Error E0318 needs a span label, a note, and an updated title, updating it from:

error[E0318]: cannot create default implementations for traits outside the crate they're defined in; define a new trait instead
  --> src/test/compile-fail/typeck-default-trait-impl-outside-crate.rs:13:1
   |
13 | impl Copy for .. {}
   | ^^^^^^^^^^^^^^^^^^^

To:

error[E0318]: cannot create default implementations for traits outside the crate they're defined in
  --> src/test/compile-fail/typeck-default-trait-impl-outside-crate.rs:13:1
   |
13 | impl Copy for .. {}
   | ^^^^^^^^^^^^^^^^^^^ `Copy` trait not defined in this crate
   |
   = note: define a new trait instead 

Bonus: narrow the span to focus on the foreign trait
