Fabric: Unification of constructor signature of ComponentDescriptors

Summary:
This is the first step to migrate the registration of Android-specific `ComponentDescriptors` to `ComponentDescriptorProviderRegistry`.
`ComponentDescriptorProviderRegistry` is a never API for component registration that supports reactive registration and simplified signatures for `registry` (`add`) method.

It's tedious to keep those signatures in sync with the base class (`ComponentDescriptor`), we have an idea how to make it better by using a single struct with all params but a migration to that will be a separate effort.

The changes are pure syntactical.
