This migrates the `String` implementation from using JS interop to explicit host imports for the standalone target. This moves a few helper methods shared between the JS and standalone targets to `dart:_string_helper`. This also moves the embedder regexp implementation to `dart:_string` to be able to access internals in some string methods (similar to how the JS implementation special-cases `JSSyntaxRegExp`). This removes the final real use of JS-interop in the standalone target. So, we can: - Remove internal JS helper libraries from the target. - Skip JS-interop transformations in the compiler. - Stop emitting a helper module and support script. Because `js_interop` is imported in `dart:_wasm`, we can't remove the library entirely. This replaces it with a stub to avoid compilation errors, a proper removal is tracked in dartbug.com/63166.
