new feature: List deleted objects that haven't been permanently removed about opendal HOT 3 OPEN

Hi, I believe listing deleted objects is an orthogonal feature compared to listing versioned objects. Some services that don't enable versioning can still have features like "soft delete," such as Azure Blob Soft Delete.

So all the following cases are possible:

• List active files: list_with(path)
• List active files along with non-current files: list_with(path).version(true)
• List active files along with deleted files: list_with(path).deleted(true)
• List all files (active, non-current, deleted): list_with(path).version(true).deleted(true).

There is a problem in #5106. when performing a simple DELETE in S3, a delete marker is inserted as the current version. In the response from ListObjectVersions, the delete markers are placed in DeleteMarker container, while other versions of the object are in the Version container. so currently, the List_with(path).version(true) will return all object versions excluding delete marker.

Understood. I'll revise this issue accordingly.
