[SPARK-38526][SQL] Fix misleading function alias name for RuntimeReplaceable

[cloud-fan]

What changes were proposed in this pull request?

This PR uses a manual recursion to replace RuntimeReplaceable expressions instead of transformAllExpressionsWithPruning. The problem of transformAllExpressionsWithPruning is it will automatically make the replacement expression inherit the function alias name from the parent node, which is quite misleading. For example, select date_part('month', c) from t, the optimized plan in EXPLAIN before this PR is

Project [date_part(cast(c#18 as date)) AS date_part(month, c)#19]
+- Relation default.t[c#18] parquet

Now it's

Project [month(cast(c#9 as date)) AS date_part(month, c)#10]
+- Relation default.t[c#9] parquet

Why are the changes needed?

fix misleading EXPLAIN result

Does this PR introduce any user-facing change?

no

How was this patch tested?
