[Refactor]: This CL refactors a few things in ComponentDescriptor.

  * Moves `abstract` methods in `ComponentDescriptor` to the top of the class so that it's easier to tell which methods contributes to the AutoValue equals/hashcode.
  * Moves `ComponentDescriptorFactory` directly to a nested class, `ComponentDescriptor.Factory`, to be more consistent with how structure other descriptors like `ModuleDescriptor`/`ModuleDescriptor.Factory`.
  * Moves `CancellationPolicy` class definition out of `ComponentDescriptor` since it's not directly related to that class.
