ArrayPrepend/ArrayAppend/ArrayInsert does not equal derived component type
(was: Use explicit casting if inserted element type in
ArrayPrepend/ArrayAppend/ArrayInsert does not equal derived component type)

> Issue Type: Bug
> Components: core
> Affects Versions: 1.35.0
> Reporter: Ran Tao

> If we run the expression below in calcite, it will cause exception:
> {code:java}
> array_prepend(array[1], cast(2 as tinyint));
> array_append(array[1], cast(2 as tinyint)) {code}
> {noformat}
> java.lang.ClassCastException: class java.lang.Byte cannot be cast to class
> java.lang.Integer (java.lang.Byte and java.lang.Integer are in module
> java.base of loader 'bootstrap')

> however, the correct spark result is:
> {code:java}
> spark-sql (default)> select array_prepend(array(1), cast(2 as tinyint));
> [2,1]
> Time taken: 0.123 seconds, Fetched 1 row(s) {code}
> {code:java}
> spark-sql (default)> select array_append(array(1), cast(2 as tinyint));
> [1,2]
> Time taken: 0.206 seconds, Fetched 1 row(s) {code}
> Actually we need to make explicit casting when element type not equals
> derived component type, so we can get an isomorphic result list (a result
> list has same operand's type) in runtime and get right results finally.
