[WIP] Add ability to skip or transform page encoding statistics in Parquet metadata

[etseidl]

Which issue does this PR close?

• Closes Reduce allocations in ParquetMetaData for improved performance #8518.

Rationale for this change

This builds on #8763 to add options to either skip decoding of the page encoding statistics array, or transform it to a bitmask. This gets rid of the last of the heavy allocations in the metadata decoder.

What changes are included in this PR?

Adds new options to ParquetMetaDataOptions. Also adds more metadata benchmarks.

Are these changes tested?

Yes

Are there any user-facing changes?

No, just adds new field to ColumnChunkMetaData.

Skipping the stats is not any faster than turning them into a mask 😮.
