Mark McCaskey 6a5efcda98 Update wasi-tests to test multiple versions of WASI
This change also cleans up the `wasi-test` generation a bit.  It's
actually still really, really messy, but at least now it's split up
into easier to understand chunks.

There's still a lot of low-hanging fruit in terms of improving the
readibilty and maintainability of the code.

Most of the files here are generated.

_common.rs is a file containing a macro that the generated tests use to avoid code duplication.

If you want to add new features, edit _common.rs and wasi-tests/build/wasitests.rs to use the changed macro.
