Also share drop-glue when compiling with -Zshare-generics (i.e. at opt-level=0) This PR adds drop-glue to the set of monomorphizations that can be shared across crates via `-Zshare-generics`. This version of the PR might have detrimental effects on performance as it makes lots of stuff dependent on a single query results (`upstream_monomorphizations_for(def_id_of_drop_in_place)`). That should be fixable but let's do a perf run first. Potentially fixes issue #64140. (cc @alexcrichton) The changes here are related to @matthewjasper's #67332 but should be mostly orthogonal. r? @ghost

Hard to get a better try run than that :) r=me on the code here too |

Hm, I find the results a bit underwhelming actually. Let's see if having a separate query drop-glue improves things. If not, merging this simpler version is good too. There's some nice cleanup/documentation in there. |

This reduces the amount of invalidated data when new types are add to upstream crates.
