This commit addresses an issue with the RISC-V sync builtins by relocating and renaming atomic unspec enums to the unspecv enum. This change involves modifications to sync.md, sync-rvwmo.md, and sync-ztso.md, ensuring consistency and proper functionality of atomic operations on the RISC-V architecture.
