This PR improves our reasoning about when to (and, more importantly, when not to) create deferred type references. We now create fewer deferred type references which improves overall compile times for the repro in #36566 by around 4%.

Fixes #36566.

The user suite test run you requested has finished and failed. I've opened a PR with the baseline diff from master.

Tests look clean. Only change is a minor type ordering difference in a few error messages in RWC.
