Comet query with range frame will fail

[viirya]

Describe the bug

I found this issue while fixing CI failures in #651.

The following errors happens many times:

[info]   java.lang.ClassCastException: class java.lang.Long cannot be cast to class java.lang.Integer (java.lang.Long and java.lang.Integer are in module java.base of loader 'bootstrap')
[info]   at scala.runtime.BoxesRunTime.unboxToInt(BoxesRunTime.java:103)
[info]   at org.apache.comet.serde.QueryPlanSerde$.windowExprToProto(QueryPlanSerde.scala:281)

It is because we don't separate RangeFrame and RowFrame for window expression support. Looks like we only support RowFrame which can take integers as upper and lower bounds. So the current code just tries to cast upper and lower bound expression values into Int.

For RangeFrame, it can accept more data types. Once we do the casting there, it causes the errors.
