Is your feature request related to a problem or challenge?

Part of https://github.com/apache/datafusion/issues/10922

We are adding APIs to efficiently convert the data stored in Parquet's "PageIndex" into ArrayRefs -- which will make it significantly easier to use this information for pruning and other tasks.

Describe the solution you'd like

Add support to StatisticsConverter::min_page_statistics and StatisticsConverter::max_page_statistics for the types above

https://github.com/apache/datafusion/blob/a923c659cf932f6369f2d5257e5b99128b67091a/datafusion/core/src/datasource/physical_plan/parquet/statistics.rs#L637-L656

Describe alternatives you've considered

You can follow the model from @Weijun-H in https://github.com/apache/datafusion/pull/10931

1. Update the test for the listed data types to be Check::Both, following the model of test_int64 https://github.com/apache/datafusion/blob/a923c659cf932f6369f2d5257e5b99128b67091a/datafusion/core/tests/parquet/arrow_statistics.rs#L506-L529
2. Add any required implementation in get_datapage_statistics: https://github.com/apache/datafusion/blob/459afbb3a180d31e7cdefffb46f033069aa47408/datafusion/core/src/datasource/physical_plan/parquet/statistics.rs#L624 (follow the model of the row counts, https://github.com/apache/datafusion/blob/2f4347647172f6997448b2e24d322b50c856f3a0/datafusion/core/src/datasource/physical_plan/parquet/statistics.rs#L90)

Typically the change to the test looks like

- check: Check::RowGroup, 
+ check: Check::Both,
