Bluetooth: Add config option to disable security checks

Browse source 
This adds CONFIG_BT_CONN_DISABLE_SECURITY which can be used to disable
security checks for incoming requests enabling to test accessing GATT
attributes and L2CAP channels that would otherwise require
encryption/authentication in order to be accessed.

It depends on BT_TESTING to indicate to the users that this is a
testing feature which shall not be used in production.
