[wasm] Wasm function imports.
...
I switched from a WasmImports object to a builder pattern:
module.instantiate().addMemory(...).addFunction(...).build();

Switch wasmer FFI boilerplate to new API
...
Broadly speaking, the new API is very similar to the old one. The only
public facing change is that you can't make a memory by itself anymore.
You need to construct if from a store, which is owned by a module.
The new API no longer passes structs by value, so I was able to delete
the wasmer_wrapper.cc, and the files I had copied from the wasmer repo.
The new API is also a lot more verbose, so it made more sense to write
a script to generate the FFI boilerplate, rather that write it all
manually.
All the migrated tests that were passing before this refactor are still
passing.

[vm] Wasm memory exports, and emscripten hello world
...
I got the hello world wasm file from the emscripten team and got it
running using a fake implementation of WASI's fd_write function. This
necessitated adding support for memory exports.

Implement a basic WASM API using wasmer.
...
Currently this only supports functions that take and return numeric
types. Byte arrays, and callbacks will come later, in a separate
wrapper package.
