lib: Add SRv6 flavors manipulation macros
`struct seg6local_context` contains a `struct seg6local_flavors_info`
that carries SRv6 flavors information. The `seg6local_flavors_info`
data structure contains a field `flv_ops` that indicates which flavors
are enabled for the `seg6local` nexthop. `flv_ops` is a bit-map where
each bit indicates if a particular SRv6 flavor is enabled (bit set to
1) or not (bit set to 0).
This commit defines some macros that can be used to manipulate the SRv6
flavors bit-map:
* CHECK_SRV6_FLV_OP(OPS,OP) - check if a particular flavor is enabled;
* SET_SRV6_FLV_OP(OPS,OP) - enable a particular flavor (OP);
* UNSET_SRV6_FLV_OP(OPS,OP) - disable a particular flavor (OP);
* RESET_SRV6_FLV_OP(OPS) - disable all SRv6 flavors.
