This PR pulls in the latest wit files from the wasi-filesystem repo, with the addition of just one pending upstream change to remove the nonblocking descriptor-flag.

The meat of this change is:

• the wasi:filesystem/filesystem interface has been renamed wasi:filesystem/types
• the interface removes device and inode from the descriptor-stat struct, and provides new metadata-hash family functions to replace this concept
  * these new methods are implemented in preview2 host, using std::hash::Hasher
  * the preview 1 adapters still need to fill in a device and inode in some places. I elected to fill in 1 for the device (because the stdio stream "files" use 0) and use the lower 64 bits of the metadata hash to fill in the inode.
  * the preview 1 host adapter needed to use an async fn to calculate each entry in fd_readdir, so I had to move some calculation out of the iterator map and into a for loop, done eagerly for each entry in the directory. Ideally this would be lazy for only entries in the directory that are being serialized as part of the adapter, or cache it between entries, but I didn't consider this worthwhile to invest in right now
• the new wasi:filesystem/preopens interface replaces the local wasi:cli-base/preopens. (There is no such thing as an upstream cli-base package, but morally it is in wasi-cli)

This PR pulls in the latest wit files from the wasi-filesystem repo, with the addition of just one pending upstream change to remove the nonblocking descriptor-flag.

The changes look like:

• the wasi:filesystem/filesystem interface has been renamed wasi:filesystem/types. This resulted in lots of renaming across the repo. For the main filesystem impl I use the new types:: module prefix but in most other places I followed use ...::filesystem::types as filesystem; to make it clearer to read.
• the interface removes device and inode from the descriptor-stat struct, and provides new metadata-hash family functions to replace this concept.
  * these new methods are implemented in preview2 host, using std::hash::Hasher to hash the device and inode of the file.
  * the preview 1 adapters still need to fill in a device and inode in some places (fd_filestat_get and fd_readdir). I elected to fill in 1 for the device (because the stdio stream "files" use 0) and use the lower 64 bits of the metadata hash to fill in the inode.
  * the preview 1 host adapter needed to use an async method to calculate each inode in fd_readdir, so I had to move some calculation out of the iterator map and into a for loop, done eagerly for each entry in the directory. Ideally this would be lazy for only entries in the directory that are being serialized as part of the adapter, or cache it between entries, but I didn't consider this worthwhile to invest in right now.

I think this looks great! Just had a question about the hasher choice before merging.

Why not use std::collections::hash_map::DefaultHasher here instead?
