Is your feature request related to a problem or challenge? Please describe what you are trying to do.
We have begun implementing BatchCoalescer for the usecase described in #6692

This ticket tracks additional follow on work:

• [coalesce] Implement specialized BatchCoalescer::push_batch for PrimitiveArray #7763
• [coalesce] Implement specialized push_batch_with_filter for primitive array #7762
• [coalesce] Implement specialized BatchCoalescer::push_batch for StringArray #7764
• [coalesce] Special case BatchCoalescer / GenericInProgressArray when multiple batches are pushed in with the same buffer #7765

Additional context

• the use case is described in detail here Optimize take/filter/concat from multiple input arrays to a single large output array #6692
