feat: Improve argument types of initialize functions

[shun-shobon]

Although WebAssembly.instantiate() can accept BufferSource (ArrayBuffer | ArrayBufferView) and WebAssembly.Module, this library only accepts ArrayBuffer is the only one accepted. So I made it so that it accepts BufferSource and WebAssembly.Module with initYoga.
This may help with things like CF Workers where only compiled WASM is available.
