Update to the next version of the witx crate

Browse Source 
This commit updates to the 0.9 version of the witx crate implemented in
WebAssembly/wasi#395. This new version drastically changes code
generation and how we interface with the crate. The intention is to
abstract the code generation aspects and allow code generators to
implement much more low-level instructions to enable more flexible APIs
in the future. Additionally a bunch of `*.witx` files were updated in
the WASI repository.

It's worth pointing out, however, that `wasi-common` does not change as
a result of this change. The shape of the APIs that we need to implement
are effectively the same and the only difference is that the shim
functions generated by wiggle are a bit different.
