[SPARK-47373][SQL] Match FileSourceScanLike to get metadata instead o…

…f FileSourceScanExec

### What changes were proposed in this pull request?

When get Spark Plan info, we should match basic trait `FileSourceScanLike` to get metadata instead of matching
subclass `FileSourceScanExec`.

So that user-define file scan operators(which extend `FileSourceScanLike`) can be matched.

### Why are the changes needed?

Match user-define file scan operators.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
Exists Unit Test

### Was this patch authored or co-authored using generative AI tooling?
No

Closes apache#45491 from zwangsheng/SPARK-47373.
