audio/transport: Propagate errors from avrcp_set_volume to DBus

Any error while setting absolute volume on the peer, or notifying the
peer of changes was previously going completely unnoticed.  Propagate it
to the logs and back to the DBus "Volume" property setter so that they
aren't misled into thinking that the AVRCP command succeeded.

Note that an error is mostly harmless when the setter of the property is
an audio sink and the peer the audio source: in this case we're only
_notifying_ the peer of the change when it has already been applied on
the sink.

Also improve the other two error messages to more closely describe what
was "invalid" about the argument.

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.

media: clear the right transport when clearing BAP endpoint

Each configured BAP stream is associated with a transport, and only that
transport should be cleared when the stream's configuration is cleared.

This is required for multiple BAP clients to use the same Media1
endpoint, which is what we should aim for to follow the spirit in which
the endpoints work in ASCS.  Sound servers generally can handle this,
since the *Configuration calls provide the transport paths, and for
different clients they are associated with different devices.

shared/bap: fix local endpoint state to be per-client

ASCS v1.0 Sec. 4.1: "For each ASE characteristic (distinguished by their
attribute handles), the server shall expose separate ASE characteristic
values for each client."  In shared/bap.c, the ASE chrc value is
contained in bt_bap_endpoint struct.

As implemented currently, the same local ASE chrc value is shared
between all clients, in contradiction with the above.  Namely, the
bt_bap_endpoint is looked up based on the gatt_db_attribute handles, in
bap_get_endpoint and bap_get_endpoint_id, but the handles correspond to
the ASCS registrations, and do not depend on which client is in
question.

Fix this by moving the endpoint states to the bt_bap BAP session struct,
so that the ASE state is associated with the sessions, and each session
has separate state.
