lib: Add ifindex to SRv6 SID context

The uA behavior is associated with an interface and the IP address of
the nexthop. However, the current SID context data structure only
includes the IP address. It lacks the interface.

This commit extends the SID context data structure by adding the
ifindex. This extension allows daemons to allocate uA SIDs with
the required interface and IP address.
