Initalize Radio Hal Capabilities before Phone

A component of Phone needs access to radio hal capabilities.
This adds two requirements on how the capabilities get loaded:
  1. They need to be loaded before PhoneFactory#makeDefaultPhone
  2. They need to be loaded on a thread other than the main thread
As a result, the loading code is taken out of
PhoneConfigurationManager and into its own class which uses a
thread other than main.

Test: Temporarily added radio hal capabilities check
  within IccPhoneBookInterfaceManager and checked logs.
