[FEA] [Audit] potential performance improvement in Scala 2.13: Replace explicit ArrayOps#toSeq with s.c.immutable.ArraySeq.unsafeWrapArray

[res-life]

Is your feature request related to a problem? Please describe.
Scala 2.13 changed the behavior for the toSeq API, it does with collection copy.
Scala 2.12 does not copy for toSeq.
So Apache Spark posted a commit (apache/spark@8a4890ddb55) : Replace explicit ArrayOps#toSeq with s.c.immutable.ArraySeq.unsafeWrapArray.
This commit has potential benefits for performance for Scala 2.13.
We should do the similar change as Spark did.
Refer to Spark code:

private[spark] object ArrayImplicits {

  implicit class SparkArrayOps[T](xs: Array[T]) {

    /**
     * Wraps an Array[T] as an immutable.ArraySeq[T] without copying.
     */
    def toImmutableArraySeq: immutable.ArraySeq[T] =
      immutable.ArraySeq.unsafeWrapArray(xs)
  }
}

Describe the solution you'd like
Maybe:

• Copy Spark code: ArrayImplicits, we can not refer to this utility directly because it's only in Spark 4.0
• search all the toSeq
• Change from toSeq to toImmutableArraySeq
