Add test for consuming interface types inputs (#1900)

Browse Source 
This commit adds a test suite for consuming interface types modules as
input and producing a JS polyfill output. The tests are relatively
simple today and don't exercise a ton of functionality, but they should
hopefully cover the breadth of at least some basics of what wasm
interface types supports today.

A few small fixes were applied along the way, such as:

* Don't require modules to have a stack pointer

* Allow passing `*.wat`, `*.wit`, or `*.wasm` files as input to
  `wasm-bindgen` instead of always requiring `*.wasm`.
