alexcrichton opened PR #12327 from alexcrichton:update-wit-vendoring to bytecodealliance:main:

This PR is a "subset" of #12250 where it only changes how WITs are vendored without actually changing the versions of any of the WITs. Due to using wkg instead of curl + tar the WITs themselves are textually changing in this PR, but their meaning isn't changing. Instead what's happening is they're all getting merged into one large *.wit-per-package.

The goal here is to split out this step from #12250 to first change how WITs are managed and then subsequently update the WITs (also related to #12247). By updating how WITs are managed we also unblock the ability to update in Wasmtime since per-proposal repos have been sunset for WASI meaning that structural changes to the update script are required no matter what to update beyond our current version.

I'll note that this additionally updates to wit-bindgen 0.51 (currently being released) which is required to read the new WITs, related to fixing some WIT bugs in wasm-tools.
