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. Changelog: [Internal] Internal changes in Fabric. Reviewed By: mdvacca Differential Revision: D18010488 fbshipit-source-id: 4cbfdbcae235b32a94b38df2095c956299764e59
