core: profile: Add accept function

This patch introduces the "accept" function to btd_profile. The purpose
of this function is to notify a profile when a btd_service is ready to
interact with and will be called by btd_device when a bt_gatt_client
becomes ready (MTU exchange and discovery has been completed). This is
initially meant to be optional for non-GATT based profiles but could be
generalized for them in the future.
