This commit goes through the dependencies that wasmtime has and updates versions where possible. This notably brings in a wasmparser/wast update which has some simd spec changes with new instructions. Otherwise most of these are just routine updates.
This is the wasmtime-wast crate, which contains an implementation of WebAssembly's
"wast" test scripting language, which is used in the
WebAssembly spec testsuite, using wasmtime for execution.
