[HUDI-6567] ExpressionEvaluators numeric types conversion support

[Alowator]

Change Logs

Add numeric types conversion in ExpressionEvaluators::compare method

Impact

For table:
table tbl (a: bigint)

data skipping work only if both types are the same. If we use
select * from tbl where a > 10
data skipping will not work, we have to use explicit cast:
select * from tbl where a > cast(10 as bigint)
this PR fixes it.

BigDecimal - the most common type of Byte, Short, Integer, Long, Float, Double and BigDecimal
So the most simple way to compare all this numeric types - cast them to BigDecimal (of course without information lose).
Also BigDecimal stores Integer types as primitive long inside.

Can we write some test cases for it.

[Alowator]

@danny0405 tests are written, pr could be reviewed

[Alowator]

@danny0405 if there are no questions, it could be merged

[danny0405]

Can we write a separate test for all the data types instead of modifying existing test. We just need to trigger the comparison of different data types. For each of the data type, test the comprison of it to all the other data types.

Just a simple Great Than(GT) comparision should be enough ~
