[CORE] Improve merge fallback reason

[ulysses-you]

What changes were proposed in this pull request?

A logical link can map to several physical plan which would cause the fallback reason loss. e.g., the logical link of FilterExec(FileSourceScanExec) is same with FileSourceScanExec. So this pr adds all reason into that logical link to make sure we do not lose any fallback reason.

Besides, this pr reduces the noisy fallback reason which is produced by ExpandFallbackPolicy if there already exists fallback reason.

How was this patch tested?
