deps,src,test: update to uvwasi 0.0.3
This commit updates to uvwasi 0.0.3, which implements a newer version of the WASI spec, snapshot_1. Since the WASI API has changed, this also requires updating the WebAssembly memory interfacing logic and recompiling the WASI tests with a version of wasi-libc that supports snapshot_1.
