feat: append EntryMode to Entry

[suyanhanx]

We should directly provide the EntryMode in the Entry, otherwise, they have to check the stat of each path one by one.

Or maybe we can add a new API like readdir.

Makes sense. Mode is required to be set in Metadata so we don't need to query it from entry. We can remove Mode from Metakey and provide mode at entry directly.

Do you want implement this part?

Count me in.

This doesn't conflict, right?

It's doesn't make sense to provide Metakey::Mode after mode() provided at Entry

No. I think this level of redundancy is still acceptable.
After all, the Mode of Entry also comes from the metadata.

Ok, let's add mode() -> EntryMode and is_file & is_dir first.
