net: qrtr: Add dynamic node id configuration

Browse Source 
Add support to configure the node id through defconfig. This is useful
for targets that are unable to configure the node id through qrtr-ns
because of security reasons. The local node id can still be overridden
by the ns if it is capable.

This option is used to configure the QRTR Node ID for the local
processor. The node ID published to other nodes within the system.
This value can be overridden by the name service application. This
option is for configurations where Node ID needs to be customized
but the name service application is not priveleged enough to use
netlink sockets.
