DAOS-18766 container: use request RPC version for filter

[wangshilong]

1. Pass the pool filter RPC version down to ds_cont_filter() and use it when reading container info so the returned layout matches the incoming request.
2. remove stale ds_cont_rpc_protocol() lookups from the set-prop path, where request decoding already follows rpc->cr_opc.

Steps for the author:

• Commit message follows the guidelines.
• Appropriate Features or Test-tag pragmas were used.
• Appropriate Functional Test Stages were run.
• At least two positive code reviews including at least one code owner from each category referenced in the PR.
• Testing is complete. If necessary, forced-landing label added and a reason added in a comment.

After all prior steps are complete:

• Gatekeeper requested (daos-gatekeeper added as a reviewer).
