This PR adds an initial version for deprecated utilities. Right now it's
hardcoded to just the `order-none` utility.
This means that `order-0` and `order-[0]` will not be migrated to
`order-none` anymore. We did that automatically because we prefer named
utilities over bare values and arbitrary values.
With this PR, `order-none` is ignored.
Similarly, `order-none` will be migrated to `order-0` instead (defined
in a separate migration for deprecated values). Made it a new migration
instead of using the legacy migration because there all utilities still
exist, but are defined differently (e.g.: `shadow`, `shadow-sm`,
`shadow-xs`).
This PR is also an initial version, it doesn't add any form of
`deprecated` flag or feature on a per-utility implementation basis. This
therefor has the side effect that if you have a custom `order-none`
defined, that it will also be ignored during migrations.
## Test plan
1. Added tests to ensure the `order-0` is not migrated to `order-none`
2. Added tests to ensure `order-none` is migrated to `order-0` (if it's
safe to do so, the signature is still computed to ensure the output is
the same).
3. Ran this on the Tailwind Plus codebase and ensured that `order-0` is
not migrated to `order-none` and that `order-none` is migrated to
`order-0`.
