packed: rewrite Teddy to use generic Vector interface
While this does technically rewrite Teddy, we don't really do any core changes to how it previously worked. We mostly just shuffle and re-organize code so that it's written to use a generic vector type instead of explicitly specialized to __m128i and __m256i. We also use this opportunity to introduce a sprinkling of const generics, which helps reduce code duplication even more. We also switch from an enum for dispatching between Teddy variants to dynamic dispatch via a trait. Benchmarks suggest there really isn't any meaningful difference here, and I kind of prefer the dynamic dispatch route for difficult to explain reasons. But I might waffle on this. And of course, the point of the exercise, we introduce an implementation of the Vector trait for `u8x16_t` on `aarch64`. Kudos to the sse2neon[1] project for making that port much faster than it would have been. [1]: https://github.com/DLTcollab/sse2neon

| These benchmarks come from [rebar's curated benchmark set]. | ||
| We don't copy all of the benchmarks from there. Just the ones where the | ||
| `aho-corasick` crate is likely relevant. For example, for the regex | ||
| `(?i)Sherlock Holmes`, a small set of prefix literals is extracted that results | ||
| in a Teddy searcher being used. So we specifically benchmark the literals that | ||
| are extracted (at time of writing). | ||
