[FRR]: Add missing no static-sids command

[cscarpitta]

Bring PR FRRouting/frr#18263 from FRR mainline to SONiC to add the missing no static-sids command.

---

Currently, when the user tries to delete all static SIDs with the no static-sids command, staticd returns an error.

router# config
router(config)# segment-routing
router(sr)# srv6
router(srv6)# no static-sids
% Unknown command: no  static-sids

The problem is the static-sids does not support the no form.

This PR enables the no form for the static-sids command.

router# config
router(config)# segment-routing
router(sr)# srv6
router(srv6)# no static-sids

Thanks for bringing the fixes in SONiC. After internal discussion, we concluded that we should keep these fixes in master for now for the safety of 202412 release.

BTW, this PR is now using 83 index number in the series file, which will cause a conflict with the #21707 PR once that is merged.

@BYGX-wcr Many thanks for the review. I changed the index number of the patch file.
