* Support parsing the text format in `wasmtime` crate This commit adds support to the `wasmtime::Module` type to parse the text format. This is often quite convenient to support in testing or tinkering with the runtime. Additionally the `wat` parser is pretty lightweight and easy to add to builds, so it's relatively easy for us to support as well! The exact manner that this is now supported comes with a few updates to the existing API: * A new optional feature of the `wasmtime` crate, `wat`, has been added. This is enabled by default. * The `Module::new` API now takes `impl AsRef<[u8]>` instead of just `&[u8]`, and when the `wat` feature is enabled it will attempt to interpret it either as a wasm binary or as the text format. Note that this check is quite cheap since you just check the first byte. * A `Module::from_file` API was added as a convenience to parse a file from disk, allowing error messages for `*.wat` files on disk to be a bit nicer. * APIs like `Module::new_unchecked` and `Module::validate` remain unchanged, they require the binary format to be called. The intention here is to make this as convenient as possible for new developers of the `wasmtime` crate. By changing the default behavior though this has ramifications such as, for example, supporting the text format implicitly through the C API now. * Handle review comments * Update more tests to avoid usage of `wat` crate * Go back to unchecked for now in wasm_module_new Looks like C# tests rely on this?
