Optimize inner product, update boilerplate, remove bad benchmarks (#7428)

## Summary

Tracking issue: #7297

Optimizes inner product with manual partial sum decomposition (because
the compiler can't optimize this because float addition is not
associative).

Also removes the old benchmarks as they no longer really time the
correct thing anymore. The real benchmarks will be finished here:
#7399. This change also adds
the `vortex-tensor/src/vector_search.rs` file to support that soon.

## Testing

N/A
