[CARBONDATA-3403]Fix MV is not working for like and filter AND and OR queries

Problem:
MV table is not hit during query for like and filter AND and OR queries,
When we have like or filter queries, the queries will have literals which will be case sensitive to fetch the data.
But dring MV modular plan generation, we register the schema for datamap where we convert the complete datamap query to lower case, which will even convert the literals.
So after modular plan generation of user query, during matching pahse of modular plan of datamap and user query, the semantic equals fails for literals, that is Attribute reference type.
Solution: Do not convert the query to lower case when registering schema, that is when adding the preagg fun to query. So it will be handled for MV
For preaggregate, instead converting complete query to lowercase, convert to lower case during ColumnTableRelation generation and createField for preaggregate generation, so it will be handled for preaggregate.

This closes #3242
