The Clear Asset operator (`ASSET_OT_clear`) now clears the Fake User. This makes it symmetrical with the Mark Asset (`ASSET_OT_mark`) operator, which sets Fake User to ensure assets are always saved to disk. Clear Asset now also has a `set_fake_user` boolean option, which allows users to Clear Asset and set Fake User in one go. The asset browser now shows these options in the context menu: - Clear Asset: also clears Fake User. This makes it possible to actually remove assets from the blend file without leaving the Asset Browser. - Clear Asset (Set Fake User): keeps the Fake User bit set. This makes it possible to "hide" the asset from the asset browser, without loosing the actual data. Internally, the `ED_asset_clear_id(id)` function now always clears the Fake User bit. If it was intended that this bit was kept set, it's up to the caller to explicitly call `id_fake_user_set(id)` afterwards.
