Add support to union of maps, tables and array of maps and tables

[MohamedSabthar]

Description:
Current serdes implementation doesn't support unions of map<>, table<>, map<>[] and table<>[] due to name collision issue. Ideally we need to support this feature.

Ex:

type RecordType record {
   int score;
};
type UnionType map<int>|map<RecordType>;

To generate the schema for the UnionType in protobuf level, the union members should have unique names. One way to avoid name collision is to allow the user to use the map type with a reference types as below.

type RecordType record {
   int score;
};
type ScoreWithIntConstraint map<int>;
type ScoreWithRecordConstraint map<RecordType>;;
type UnionType ScoreWithIntConstraint|ScoreWithRecordConstraint;

This way we could eliminate the name collision issue in protobuf level and generate a schema for UnionType as below,

message UnionBuilder {
 message ScoreWithIntConstraint___MapBuilder {
   ...
 }
 message ScoreWithRecordConstraint___MapBuilder {
   ...
 }
 ScoreWithIntConstraint___MapBuilder ScoreWithIntConstraint_unionField = 1;
 ScoreWithRecordConstraint___MapBuilder ScoreWithRecordConstraint_unionField = 2;
}

Describe your task(s)
Implement above solution and throw an error for non referenced member (table, map) types.
