dirstate: Skip no-op conversion in Rust DirstateMap::set_v1 Now that the `DirstateItem` python class is implemented in Rust containing a `DirstateEntry` value, use that value directly instead of reconstructing it from v1 data. Also rename from `set_v1` since dirstate-v1 data is not used anymore. Differential Revision: https://phab.mercurial-scm.org/D11487
