This PR adds benchmarks with a custom `Measurement`. In this case, we
measure RSS and cumulative memory usage (target `arrow_reader_peak_memory`).
I am not sure if the benchmark bot will like those new units:
```
arrow_array_reader/ListArray_peak_memory/Int32List/no NULLs
time: [836.51 KiB 836.51 KiB 836.51 KiB]
arrow_array_reader/ListArray_peak_memory/Int32List/half NULLs
time: [482.01 KiB 482.01 KiB 482.01 KiB]
arrow_array_reader/ListArray_peak_memory/Int32List/90pct NULLs
time: [271.95 KiB 271.95 KiB 271.95 KiB]
arrow_array_reader/ListArray_peak_memory/Int32List/99pct NULLs
time: [217.96 KiB 217.96 KiB 217.96 KiB]
```
