[parquet-mr] Implement specification-compliant floating point comparison

Currently, the floating point comparison order defined by parquet-format is ambigous and different implementations use different orderings. Once the specification is made unambigous (PARQUET-1222), implementations should be updated to conform to it.

该 issue 没有指出 parquet-java 中的文件、测试或入口点。首先阅读被阻塞的 issue PARQUET-1222《Specify a well-defined sorting order for float and double types》，然后找出比较实现及其测试；当 parquet-java 符合最终确定的规范时，即视为完成。
