  1. [CALCITE-1178] Allow SqlBetweenOperator to compare DATE and TIMESTAMP 

    * Add implicit type coercion rules for BETWEEN operator and add test
cases
* For comparison of NUMERIC and CHARACTER, we coerce the CHARACTER to
NUMERIC type which is breaking change.(Before this patch, CHARACTER would
be coerced to INT during sql-to-rel conversion)
* For "DATETIME and CHARACTER" comparison and equality, add coercion rules during sql
node validation, before this patch, the coercion happens during sql-to-rel conversion
* Some code refactoring for TypeCoercionConverterTest
