[CARBONDATA-270] Double data type value comparison optimization
[Description] Double data type value comparison
optimization,EqualsToExpression evaluation for double values first check for
the equality of nan values and then the double value comparison happens, since
nan comparison scenarios are rare we can push the comparison of nan after the
double value comparison.
Already present UT testcases can verify the feature modification impact.
