Rollup merge of #92191 - jackh726:issue-89352, r=nikomatsakis
Prefer projection candidates instead of param_env candidates for Sized predicates

Fixes #89352

Also includes some drive by logging and verbose printing changes that I found useful when debugging this, but I can remove this if needed.

This is a little hacky - but imo no more than the rest of `candidate_should_be_dropped_in_favor_of`. Importantly, in a Chalk-like world, both candidates should be completely compatible.
