Convert arc_play_store_enabled_preference_handler_unittest.cc to use IdentityTestEnvironment

IdentityManager currently wraps other signin APIs including SigninManager
and PO2TS. This CL migrates ArcPlayStoreEnabledPreferenceHandlerTest
and IdentityManager's testing facility IdentityTestEnvironment, and
hides the test internals from SigninManager APIs.

This is part of the servicification effort.
