Implement native interleave for ListView

[vegarsti]

Closes #9342.

This PR adds a native implementation of interleave for the ListView type. Also adds a benchmark.

Performance improves by more than 30% in all cases in the benchmark:

Benchmark	Time (branch)	Change vs baseline	Speedup
list_view<i64>(0.1,0.1,20) 100	2.40 µs	−41.2%	1.70×
list_view<i64>(0.1,0.1,20) 400	6.50 µs	−36.6%	1.58×
list_view<i64>(0.1,0.1,20) 1024	15.67 µs	−38.1%	1.62×
list_view<i64>(0.1,0.1,20) 1024 4-arr	15.76 µs	−35.7%	1.55×
list_view<i64>(0.0,0.0,20) 100	1.49 µs	−41.0%	1.70×
list_view<i64>(0.0,0.0,20) 400	3.99 µs	−30.3%	1.43×

Do you mind comparing this to the fallthrough performance of #9562 ?

Oh for sure, thanks for reminding me!

Updated the description with results now. It's not looking like a win..!

[brancz]

I would say let's merge the fallthrough and iterate on this version. I'm sure there are several possibilities for optimizations.

FWIW I pushed up the branch I've had marinating locally for a month or two in case it's helpful: main...polarsignals:arrow-rs:asubiotto/lvinterleave. I believe the benchmarks showed a slight regression for interleaves of small lists, but overall the perf was an improvement. I'm not able to take a closer look right now, but sharing in case it's helpful.
