crimson/osd/object_context_loader: SnapTrim to not resolve_oid

SnapTrimObjSubEvent::remove_or_update partially resolves the to be
trimmed clone taking into account in_removed_snaps_queue.
The general resolve_oid is not suitable for this scenario.
Specifically the following check:
```
    if (std::find(
      citer->second.begin(),
      citer->second.end(),
      oid.snap) == citer->second.end()) {
       logger().debug("{} {} does not contain {} -- DNE",
                      __func__, ss.clone_snaps, oid.snap);
       return std::nullopt;
    }
```
because of earlier snap_map_modify call.

Example:
```
INFO  2024-04-07 13:44:01,118 [shard 0:main] osd - SnapTrimObjSubEvent(coid=2:e8855410:::folio011816418-576:8 snapid=8): 2:e8855410:::folio011816418-576:8 snaps [8, 7] -> {7}

...
This case will fail:
