frr: update to 10.0.1

[KanjiMonster]

Update FRR to 10.0.1 and sync with upstream.

• backported all changes applicable to kirkstone from upstream
• backported required libyang updated for FRR 10.
• updated our .bbappend as needed
• updated our .service files with the new scripts location
• reduced the PR to "r1" since upstream dropped PR from recipes (so they default to "r0")
• synced support_bundle_commands.conf with the version from FRR 10.

Changelogs here:

• https://github.com/FRRouting/frr/releases/tag/frr-10.0.1
• https://github.com/FRRouting/frr/releases/tag/frr-10.0
• https://github.com/FRRouting/frr/releases/tag/frr-9.1

FRR 10 has some breaking changes/new behavior:

• writing per-daemon configuration files is not supported anymore (reading still is)
• the parser is now more strict(?)
• OSPFv6 in P2(M)P mode now installs host-routes for all router IP addresses
