Bluetooth: Host: Add a configuration for writable name

Browse source 
In the file gatt.c, GAP service contains the Device Name
characteristic. If writable, authentication and authorization may
be defined by a higher layer specification.It means that GATT
clients can write to device name GAP characteristic without
bonding. So we add a configuration for writable name without
bonding.
