Tracking: speed up the logical optimizer

I plan to speed up the logical optimizer from two aspects:

Try to reduce the optimization rounds by making each rule generate the best plan as much as possible
Optimize the single rule's plan time.

The issue mainly tracks a to-do list, and anyone interested in the topic can follow it.

After #15744, I'll close the tracking. Let's continue if we find the specific bottleneck

I know there is still an outstanding issue with logical optimization performance #17261, maybe that should be added here
