This commit uses the `*.witx` files describing the current wasi API to reduce the boilerplate used to define implementations in the `wasmtime-wasi` crate. Eventually I'd like to remove lots of boilerplate in the `wasi-common` crate too, but this should at least be a good start! The boilerplate removed here is: * No need to list each function to add it to the `wasmtime_runtime::Module` being created * No need to list the signature of the function in a separate `syscalls.rs` file. Instead the `*.witx` file is processed in a single-use macro inside the `wasmtime-wasi` crate. This macro uses the signatures known from `*.witx` to automatically register with the right type in the wasm module as well as define a wrapper that the wasm module will call into. Functionally this is all the same as before, it's just defined in a different way now! The shim generated by this macro which wasmtime calls into only uses `i32`/`i64`/etc wasm types, and it internally uses `as` casts to convert to the right wasi types when delegating into the `wasi-common` crate. One change was necessary to get this implemented, however. The functions in `wasi-common` sometimes took `WasiCtx` and sometimes took a slice of memory. After this PR they uniformly all require both `WasiCtx` and memory so the wrappers can be auto-generated. The arguments are ignored if they weren't previously required.
