fix(guest): adapt Resolver/Loader to rquickjs 0.12

rquickjs 0.12 adds an import-attributes parameter to the module
loader traits: `Resolver::resolve` and `Loader::load` now take a
trailing `Option<ImportAttributes>` (for `import ... with { type }`).
Update StubModuleLoader's impls to match the new signatures; the stub
ignores attributes since it accepts any module for syntax validation.
