Reuse single resource jars array in the same dirs sub-dirs

[franz1981]

Most of the times jar resources subdirs can share a single value array of resources, saving reallocating it each time.

This could be pushed even further; that's why is still in draft

@gsmet @Sanne this can be pushed further by:

• avoiding a linked hash set (which is backed by an hashmap :"() in favour of a growable array of the right size
• using something different from strings as keys

This will need a lot of scrutiny and let's not backport it :).

[franz1981]

Still the most expensive number of allocations here are the substrings - which should be just views of the original string, tbh.

[Sanne]

Most of this processing for the "SerializedApplication" could be moved to build-time. Want to try that?

[franz1981]

Let's sync today for this @Sanne - which, regardless, still contains some logic error which break something

[franz1981]

I'm closing this since this is going soonish to change :pray:

[Sanne]

Ok for closing, but I still hope that any follow up could move a good chunk of all the initialization work of those data structures to build time.
