File/Asset Browser: Extend file-entry and asset handle Python API

Adds the following to `bpy.types.FileSelectEntry`:
* `id_type`: The data-block type the file represenets, if any.
* `local_id`: The local data-block it represents, if any (assets only).

And the following to `bpy.types.AssetHandle`:
* `local_id`: The local data-block the asset represents, if any.

This kind of information and the references are important for asset related
operators and UIs. They will be used by upcoming Pose Library features.
