Which issue does this PR close?

Rationale for this change

  • We need a bench to measure perf

What changes are included in this PR?

  • Added a bit-packing benchmark

  • It covers all encoding paths affected by bit
    packing:

    • PLAIN boolean encoding
    • RLE boolean encoding
    • DELTA_BINARY_PACKED for i32
    • DELTA_BINARY_PACKED for i64
    • DELTA_LENGTH_BYTE_ARRAY
    • DELTA_BYTE_ARRAY
    • Generic dictionary-index encoding
    • Arrow’s specialized byte-array dictionary-index encoding
    • Definition- and repetition-level encoding via the RLE/
      bit-packed hybrid encoder

Are these changes tested?

  • N/A

Are there any user-facing changes?
