Auto merge of #90845 - JakobDegen:adt-drop-perf, r=Mark-Simulacrum
Address performance regression introduced by #90218 As part of the changes in #90218 , the `adt_drop_tys` and friends code stopped recursing through the query system, meaning that intermediate computations did not get cached. This change adds the recursions back in without re-introducing any of the old issues. On local benchmarks this fixes the 5% regressions in #90504 ; the wg-grammar regressions didn't seem to move too much. I may take some time later to look into those. Not sure who to request for review here, so will leave it up to whoever gets it.
