Merge extended reference handling back into primary experimental branch.

[lallydd]

Added more tracking (for future diagnostics) and tracked down the last known reference leaks.

What does this PR do?

👋 is this ready for review or should this be a draft PR?

Oh I'll make it a draft PR. I want to verify it passes CI/CD and start running the benchmarks.

[lallydd]

This is a reference PR for what #20943 and its successive 2 will result in when complete. This branch contains all planned changes, lally/exp-mem held a subset.
