Enhancement to support interim Ubuntu releases (e.g. ubuntu@24.10) as build-bases for kernel snaps, backward compatibly. Triaged by maintainer; PoC PR #4914 merged but unusable as-is. Blockers #4921 and #5015 are now resolved. Not yet implemented in code.

Suggested action: keep open

Reason: The issue is triaged (labeled Status: Triaged), authored by a maintainer, and the feature is confirmed unimplemented in code (build_base for kernel snaps is still Literal["core24", "core26", "devel"]). Both referenced blockers (#4921 systemd-resolved fix, #5015 craft-platforms) are now closed, clearing the path for implementation. Last activity was ~7 months ago but the scope remains valid and unaddressed.

Issue body

### What needs to get done Per ST119, kernel snaps need to be able to declare build-bases like `ubuntu@24.10`. Support interim kernel bases as documented in the proof of concept branch (https://github.com/canonical/snapcraft/pull/4914), except in a backward compatible way. The proof of concept branch can't be used directly for 3 reasons: - written for pydantic 1 - predates craft-platforms - backward incompatible ### Why it needs to get done So kernel snaps can be created for interim releases. Interdependencies: * This feature isn't particularly useful when snapcraft can't launch 24.10 build environments (https://github.com/canonical/snapcraft/issues/4921) * This will overlap heavily with https://github.com/canonical/snapcraft/issues/5015 and will require changes to craft-platforms
