Uplift the invalid_atomic_ordering lint from clippy to rustc

- Deprecate clippy::invalid_atomic_ordering
- Use rustc_diagnostic_item for the orderings in the invalid_atomic_ordering lint
- Reduce code duplication
- Give up on making enum variants diagnostic items and just look for
`Ordering` instead

  I ran into tons of trouble with this because apparently the change to
  store HIR attrs in a side table also gave the DefIds of the
  constructor instead of the variant itself. So I had to change
  `matches_ordering` to also check the grandparent of the defid as well.

- Rename `atomic_ordering_x` symbols to just the name of the variant
- Fix typos in checks - there were a few places that said "may not be
  Release" in the diagnostic but actually checked for SeqCst in the lint.
- Make constant items const
- Use fewer diagnostic items
- Only look at arguments after making sure the method matches

  This prevents an ICE when there aren't enough arguments.

- Ignore trait methods
- Only check Ctors instead of going through `qpath_res`

  The functions take values, so this couldn't ever be anything else.

- Add if_chain to allowed dependencies
- Fix grammar
- Remove unnecessary allow
