* Experiment with holding hard references to objects being qdeleted in 515 (saves 1.1+ seconds on init times, more on prod) (#72033)
## About The Pull Request
Adds `EXPERIMENT_515_QDEL_HARD_REFERENCE`, which will queue to the GC
subsystem using hard references rather than `\ref`. This is only
possible in 515 because of the new `refcount` proc. `\ref` is very very
slow and has some nasty knock on effects, so removing its usages where
possible is good.
This is an explicit opt in define because I want to give us the ability
to test 515 on live while only testing 515 itself, not our experimental
changes. We have a few more of these we want to do so I made a separate
file for them. They're auto-defined in unit tests so we see them with
the alternate test runner. In a perfect world we'd test both on and off,
but eh.

* Keeps gc_destroyed from getting updated on every step thru the gc queue. (#72401)
Keeps gc_destroyed from getting updated on every step thru the gc queue.
Fixes logic that assumed gc_destroyed is the time the object first
qdel'ed. it used to get updated on each stage of the garbage controller
and there are 3 stages.
Added list index defines for the inner gc item list.
* test fix
* final fix
