Allow bounded generic provides methods

[evant]

This allows generic construction which can be useful in some cases, ex:
retrofit.

@Compnation abstract class NetworkComponent {
    @Provides
    inline fun <reified T: Service> retrofitService(retrofit: Retrofit): T = retrofit.create<T>()
}

A type bounds other than Any is required, otherwise the provides would be
avaialble for every injection which could easily hide other errors until
runtime.

Note: reified inline provides methods only work in the ksp backend because the
method is not accesable from kapt.
