This is consistent with the rest of the API since the attribute length
can be at most 512 bytes long.

Attribute length can be up to 512 bytes long so it needs to be at least
uint16_t, ATT already takes care that the MTU does not exceed 512 bytes.

Note: Attributes which values are bigger than the MTU need to be read
multiple time until the end since the stack cannot cache any data.

This introduce a new callback called flush to bt_gatt_attr to indicate
when and attribute can cache data, the data is automatically flushed if
regular write request happens and in case of prepare write it checks if
flush is supported otherwise return an error, then upon receiving an
execute write it perform flush over the entire database and respond
with result:
< ACL Data TX: Handle 42 flags 0x00 dlen 6
ATT: Execute Write Request (0x18) len 1
Flags: Immediately write all pending values (0x01)
> ACL Data RX: Handle 42 flags 0x02 dlen 5

The spec says that CCC shall only be persistent accross connection for
bonded devices:
'The Client Characteristic Configuration descriptor value shall be
persistent across connections for bonded devices. The Client Characteristic
Configuration descriptor value shall be set to the default value at each
connection with non-bonded devices'.
To handle this now each configuration has a valid field indicating if the
configuration is valid.

BT_GATT_CCC uses _bt_gatt_ccc internal struct to handle peer
configurations and special helpers to read and write to minimize the
code necessary to handle CCC in the task.
Note this not yet include handling of connection and disconnection but
the idea is that the core would automatically disable the configurations
while disconnected and re-enable once peer connect back.
