passing `WebAssemblyCompileOptions` to `v8::WasmModuleObject::compile`

[Yu-zh]

Hello,

Current version of v8 supports the js-string-builtins proposal: https://github.com/WebAssembly/js-string-builtins/blob/main/proposals/js-string-builtins/Overview.md#using-builtins. To enable this feature, one needs to pass the extra argument { builtins: ['js-string'] } to Webassembly.compile. This parameter is missing from the rusty_v8 api. Will this parameter be added in the future? Thanks!
