[CARBONDATA-3653] Support huge data for complex child columns Why is this PR needed? Currently complex child columns string and binary is stored as short length. So, if the data is more than 32000 characters. Data load will fail for binary and long string columns. What changes were proposed in this PR? complex child columns string, binary, decimal, date is stored as byte_array page with short length. Changed it to int length. [Just separating string and binary is hard now, to do in future] Handled compatibility by introducing the new encoding type for complex child columns Does this PR introduce any user interface change? No Is any new testcase added? Yes This closes #3562
