This can be used to tell the upper layers that connection fails,
therefore they can provide better feedback to the user. Additionally
floss will also use it for metrics.

When BT1 connected -> BT2 connected -> BT2 disconnected,
then the sound came from phone speaker before this CL.
With the CL, now the sound comes from BT1.

This registers a super basic callbacks when entering btclient which just
print what it gets in debug format.

Bug: 239470860
Test: test it with the following procedures.
1. start btclient. Pair with a Classic KBD, and Classic headset.
2. set allowlist to A2DP+HFP+AVRCP. Check btclient gets notification of
   new allowlist and the policy effect of devices are correct.
3. start scan in btclient and check if it gets notifications of policy
   effect change of new devices.

Change-Id: I0d26c70b67393a92d05f6c9598fa97db83cfa2b8

Implement the following callbacks for client.

- OnServiceAllowlistChanged:
Get the updated service allowlist

- OnDevicePolicyEffectChanged:
Get the updated policy effect, which includes
(1) list of services that are disallowed by the current policy
(2) boolean value to indicate if the device has an adapter-supported
profile that is blocked by the policy.

Admin policy will be stored in /var/lib/bluetooth/admin_policy.json

It will be updated upon a successful SetServiceAllowedlist call, and it
will be loaded upon btadapterd starts.

Bug: 239470589
Test: tested it with the following steps
Set allowed list via gdbus
check /var/lib/bluetooth/admin_policy.json is updated correctly
restart btadapterd
Get allowed list via gdbus and check if it's persistent

Bug: 239470589
Test: test it with the following procedures.
service allowed list was set by gdbus call.
1. check classic HS, Classic KB and LE Mouse can function.
2. set allowed list to a single random UUID, and check none of the
   above device can function.
3. set allowed list to A2DP+HFP, and check audio is functioning but the
   other two stay non-functioning.
4. set allowed list to HID, and check HID devices are functioning but no
   audio from the HS.
5. set allowed list to empty, and check all of the above devices are
   functioning.

This API disables the services that is not in the allowed list. A
profile is disabled by calling |disable| in topshim layer which should
call |cleanup| to the libbluetooth interface. Similarly, a profile is
re-enabled by calling |enable| in topshim and |init| of the libbluetooth
interface will be called subsequently.

However, the cleanup function of HFP and A2DP in topshim-cpp layer
haven't been implemented. By testing locally, the consequence is that
when a2dp and hfp are disabled by policy, the audio headset can still be
connected and stay connected, but there is no audio stream to the
headset nor the chromebook. Additionally, the headset could adjust the
volumn via HFP.

Implements the following APIs for topshim profiles
- enable
- disable
- is_enabled

The original logic of |initialize| is splitted into setting the
dispachers and enabling the internal interface. The new |initialize|
do the former part and |enable| do the latter part.
