Preserve bitmap-backed `RowSelection` in `ParquetAccessPlan`

[haohuaijin]

Is your feature request related to a problem or challenge?

arrow-rs#10141 allows RowSelection to be backed by a BooleanBuffer.

However, ParquetAccessPlan::into_overall_row_selection currently calls RowSelection::iter() and converts each selection into a Vec<RowSelector>. This materializes mask-backed selections as RLE and loses the bitmap backing before it reaches the Parquet reader.

This issue is blocked until DataFusion upgrades to an Arrow/Parquet release containing arrow-rs#10141.

Describe the solution you'd like

• Validate selection length using row_count() + skipped_row_count() instead of iter().
• When all row-group selections are mask-backed, concatenate their BooleanBuffers directly.
• Represent scanned row groups as all-set bitmap ranges and omit skipped row groups.
• Keep the existing selector path as the fallback for selector-backed or mixed inputs.

Describe alternatives you've considered

Converting selectors back to a bitmap in the Parquet reader does not help because the large intermediate Vec<RowSelector> has already been allocated.
