Alex Crichton 08f9eb1725 Making caching support optional in Wasmtime (#2119)
This commit moves all of the caching support that currently lives in
`wasmtime-environ` into a `wasmtime-cache` crate and makes it optional. The
goal here is to slim down the `wasmtime-environ` crate and clearly separate
boundaries where caching is a standalone and optional feature, not intertwined
with other crates.

// We test init() in exactly one test, rest of the tests doesn't rely on it.
