* Support for running Halide-compiled Wasm code in-process.
* Bindings for parameters, extern calls, etc. are established and the
* Wasm code is executed. Allows calls to realize to work
* exactly as if native code had been run, but via a JavaScript/Wasm VM.
* Currently, only the WABT interpreter is supported.
