This commit changes the C API function `wasm_module_new` to use the Rust API `Module::from_binary` which performs verification of the module, as per the C API spec. This also introduces a `EngineBuilder` type to the C# API that can be used to construct an `Engine` with the various Wasmtime configuration options. This is required to get the C# tests passing since they use reference types and multi-value. Fixes #859.
