[PR] feat(core): Add copy source version support [opendal]

   # Which issue does this PR close?
   
   Part of #7182.
   
   # Rationale for this change
   
   RFC-7182 needs a zero-overhead primitive that can copy from a specific source version. Exposing this on copy lets higher-level restore APIs reuse the existing copy abstraction instead of requiring every backend to implement a separate restore path.
   
   # What changes are included in this PR?
   
   This PR adds `copy_with_source_version` capability and `CopyOptions::source_version`, wires the option through `copy_with` and `copier_with`, and validates the capability in correctness and capability-check layers.
   
   S3 enables the capability and sends `versionId` in copy-source requests. GCS and AzBlob request builders are prepared to carry source versions, but their capabilities are not enabled yet. The S3 non-versioning CI configurations explicitly disable the new capability, and behavior tests cover copying an older source version to a new path and back to the same path.
   
   # Are there any user-facing changes?
   
   Yes. Rust users can call `.source_version(...)` on `copy_with` and `copier_with` when `Capability::copy_with_source_version` is true.
   
   # AI Usage Statement
   
   AI-assisted implementation and review were used for this PR.
