Use Metro scope annotations

Remove the local AppScope, ForScope, and SingleIn stubs now that Metro provides the same annotations directly.

Update compiler-generated annotation class IDs to emit Metro's AppScope, ForScope, and SingleIn symbols, including the scope constructor argument used by Metro's ForScope and SingleIn annotations. Refresh affected compiler test sources, FIR dumps, and integration imports to reference dev.zacsweers.metro.
