update to Wasmtime 17 and WASI 0.2.0 (#2250)

I've taken this opportunity to rename the wit directories to reflect the WASI
snapshots they correspond to.

Note that the Rust and Go SDKs continue to target the 2023-10-18 snapshot for
compatibility.  Likewise, `spin-world`.  `spin-trigger-http`, however, can
handle components targeting either 2023-10-18, 2023-11-10, or the final 0.2.0
release of WASI.
