### What changes were proposed in this pull request?
for SQL function aliases (with `setAlias=true`) added in 3.5, using replace
expression construction with `call_function` to make the output column name
consistent with SQL
### Why are the changes needed?
before this PR
```
scala> val df = spark.range(0, 10)
df: org.apache.spark.sql.Dataset[Long] = [id: bigint]
scala> df.createOrReplaceTempView("t")
scala> spark.sql("SELECT TRY_SUM(id), TRY_AVG(id) FROM t")
res1: org.apache.spark.sql.DataFrame = [try_sum(id): bigint, try_avg(id):
double]
scala> df.select(try_sum(col("id")), try_avg(col("id")))
res2: org.apache.spark.sql.DataFrame = [sum(id): bigint, avg(id): double]
scala>
scala> spark.sql("SELECT sign(-1), signum(-1)")
res3: org.apache.spark.sql.DataFrame = [sign(-1): double, SIGNUM(-1): double]
scala> spark.range(1).select(sign(lit(-1)), signum(lit(-1)))
res4: org.apache.spark.sql.DataFrame = [SIGNUM(-1): double, SIGNUM(-1):
double]
```
