Use a global cache for all downloaded binaries

This commit switches wasm-pack to using a global cache for all download binaries, living typically in a user's home directory. The intention here is to aovid creating a `bin` folder in all wasm-pack projects and additionally share downloads between projects to ensure that you're downloading a minimal number of binaries from the network. Along the way the downloading code was restructured to support a global cache, but everything should largely be as it was before! Closes #292
