GH-123516: Improve JIT memory consumption by invalidating cold executors

[savannahostrowski]

This PR succeeds #123402 and reworks the approach to use the eval breaker for the invalidation call instead of executor creation or gc (thanks @markshannon!). In experimenting, I tried a couple of different thresholds of 10k, 100k, and 1 million runs. The benchmarks for 100k and 1 million were most promising. Here are some relevant stats for quick reference:

100k
- -2.4% memory
- Roughly the same performance-wise

1 million

• -1.5% memory
• Roughly the same performance-wise

After chatting with @brandtbucher, I've opted to open this PR with the 100k threshold. One thing to note is that we are potentially a little too liberal in invalidating executors with this threshold, but with the lack of movement in performance and a more substantial decrease in memory usage, it seemed justified. We can continue to iterate here and consider making this tunable in the future.

This is a nice change, thanks!
