device: wait GATT client ready before service accept() if no cache
On device ATT attach, do not immediately call accept() for profiles, if
there is no cached data in GATT database. Instead, wait for service
resolution to complete, as likely accept() cannot succeed before that.
Several profiles (bap, vcp, midi, deviceinfo) assume that GATT
attributes are available when their accept() is called, returning
success even if not. In this case, the services never find the remote
attributes and are not operable. Other profiles (hog, batt, ...) fail
their accept which prompts core to retry after discovery, and work
correctly also in this case.
Fix the failing services by waiting for service resolution as necessary,
so profiles can assume the GATT DB has some content.
