[BugFix] skip add the alias into fieldMapping when order by expr not referenced this alias

[packy92]

Why I'm doing:

failed to execute select v1 cc, v2 cc from tbl order by v3 with error info column cc is ambiguous

What I'm doing:

order by expr may reference the alias. We need put the alias into the fieldMappings or the expressionToColumns.
if the alias not be used in the order by expr like:
select v1 cc, v2 cc from tbl order by v3
We just add the slotRef(cc) to columnRefOperator in the
expressionToColumns to ensure this projection can output v1 with alias cc, v2 with alias cc and v3.
We don't need to ensure the uniqueness of the alias in the fieldMappings.

if the alias used in the order by expr like:
select v1 v3, v2 cc from (select abs(v1) v1, abs(v2) v2, v3 from t0) t1 order by t1.v3
order by expr t1.v3 referenced the v1 with alias v3, we need set the fieldMappings to ensure order by
expr can be resolved.
