Previously the `AsyncLocker` was configured to only wait 50x500ms before timing out. This is 25secs, which is often less than a normal run of ngcc, so the chance of a timeout flake was quite high. The default is now 500x500ms, which is 250secs. If this is too high for some projects then it can be changed via the `ngcc.config.js` project file. PR Close #36838
