This commit removes all import resolution handling from the `wasmtime-jit` crate, instead moving the logic to the `wasmtime` crate. Previously `wasmtime-jit` had a generic `Resolver` trait and would do all the import type matching itself, but with the upcoming module-linking implementation this is going to get much trickier. The goal of this commit is to centralize all meaty "preparation" logic for instantiation into one location, probably the `wasmtime` crate itself. Instantiation will soon involve recursive instantiation and management of alias definitions as well. Having everything in one location, especially with access to `Store` so we can persist instances for safety, will be quite convenient. Additionally the `Resolver` trait isn't really necessary any more since imports are, at the lowest level, provided as a list rather than a map of some kind. More generic resolution functionality is provided via `Linker` or user layers on top of `Instance::new` itself. This makes matching up provided items to expected imports much easier as well. Overall this is largely just moving code around, but most of the code in the previous `resolve_imports` phase can be deleted since a lot of it is handled by surrounding pieces of `wasmtime` as well.
This is the wasmtime-jit crate, which contains JIT-based execution
for wasm, using the wasm ABI defined by wasmtime-environ and the
runtime support provided by wasmtime-runtime.
Most users will want to use the main wasmtime crate instead of using this
crate directly.
