6c3aefa0b6 Bluetooth: host: Clear CCC when clearing all keys
CCC settings was not removed when unpairing all keys.
It means CCC settings were still present in flash and were
loading at bluetooth initialization time.

Loading these orphan CCC settings would fill `bt_gatt_ccc_cfg`
configurations and would prevent to add new CCC when pairing
with a new device.

6798a421e1 Bluetooth: GATT: Ensure GATT service is registered first
Accourding to Bluetooth specification the Service Changed
Characteristic shall not have its handle changed once it has been
bonded, so this moves the GATT service to be the very first service
registered that way it is guaranteed that it won't change even if
device is flashed with a different configuration which end up changing
the handles after it.

a618ea2a5a Bluetooth: GATT: Fix not handling duplicated CCC storage
Some backends may actually contain the same key multiple times so the

write operation so this adds a flag called BT_GATT_WRITE_FLAG_CMD which

BT_ATT_ERR_WRITE_REQ_REJECTED when that flag is not set which should
indicate to the client to use write command instead.

Experiments have shown that the probability of missing advertising
packets is significantly lower with 30ms scan window compared to 10ms
scan window. This is especially the case with advertisers using a 20ms
advertising interval, which in turn is perhaps the most common one
since it's the smallest allowed by the Bluetooth 5.0 specification.

c2d62a29f0 Bluetooth: host: Require 128-bit encryption key for security level 4.
In Bluetooth 5 the definition of LE security mode 1, has changed.
LE Security Mode 1 level 4 requires authenticated LE Secure Connections
pairing with encryption using a 128-bit strength encryption key.
This also changes the behaviour when a security request and response
would end up with a security level that is lower than the one requested.
Before pairing would complete, and the link would disconnect with error
authentication failure. Instead a SMP will abort pairing with error code
authentication requirement, or encryption key size.
