zebra: Add support for SRv6 SID formats
Add functionalities to manage SRv6 SID formats (register / unregister /
lookup) and create two SID formats upon SRv6 Manager initialization:
`uncompressed-f4024` and `usid-f3216`.
In future commits, we will add the CLI to allow the user to choose
between the two formats.
