Is your feature request related to a problem or challenge?
We currently have three very similar cache implementations that combine LRU eviction with memory limits as mentioned in #20047 (comment) by @nuno-faria:
This results in duplicated logic and unnecessary maintenance overhead.
Describe the solution you'd like
These three implementations can be merged into one single generic cache implementation that supports all three use cases.
