Alex Crichton a628dc315e Shuffle around the wiggle crates (#1414) 
* Shuffle around the wiggle crates

This commit reorganizes the wiggle crates slightly by performing the
following transforms:

* The `crates/wiggle` crate, previously named `wiggle`, was moved to
  `crates/wiggle/crates/macro` and is renamed to `wiggle-macro`.

* The `crates/wiggle/crates/runtime` crate, previously named
  `wiggle-runtime`, was moved to `crates/wiggle` and is renamed to
  `wiggle`.

* The new `wiggle` crate depends on `wiggle-macro` and reexports the macro.

The goal here is that consumers only deal with the `wiggle` crate
itself. No more crates depend on `wiggle-runtime` and all dependencies
are entirely on just the `wiggle` crate.

* Remove the `crates/wiggle/crates` directory

Move everything into `crates/wiggle` directly, like `wasi-common`

* Add wiggle-macro to test-all script

* Fixup a test

wiggle-generate

This is a library crate that implements all of the component parts of the wiggle proc-macro crate.

Code lives in a separate non-proc-macro crate so that it can be reused in other settings, e.g. the lucet-wiggle crate.

Code generated by this crate should not have any references to a particular WebAssembly runtime or engine. It should instead expose traits that may be implemented by an engine. Today, it is consumed by both Lucet and Wasmtime.
