…ecompile loading (JuliaLang#56291) Fixes `_require_search_from_serialized` to first acquire all start_loading locks (using a deadlock-free batch-locking algorithm) before doing stalechecks and the rest, so that all the global computations happen behind the require_lock, then the rest can happen behind module-specific locks, then (as before) extensions can be loaded in parallel eventually after `require` returns.

Per upstream review, this is not backportable to 1.10 -- there will be too many data races and bugs in the loading process prior to 1.12 (might be possible to backport to 1.11). |
