Enable clippy::check-private-items so that missing_safety_doc will apply to private functions as well (#15161)

Browse source 
Enabled `check-private-items` in `clippy.toml` and then fixed the
resulting errors. Most of these were simply misformatted and of the
remaining:
- ~Added `#[allow(clippy::missing_safety_doc)]` to~ Removed unsafe from
a pair of functions in `bevy_utils/futures` which are only unsafe so
that they can be passed to a function which requires `unsafe fn`
- Removed `unsafe` from `UnsafeWorldCell::observers` as from what I can
tell it is always safe like `components`, `bundles` etc. (this should be
checked)
- Added safety docs to:
- `Bundles::get_storage_unchecked`: Based on the function that writes to
`dynamic_component_storages`
- `Bundles::get_storages_unchecked`: Based on the function that writes
to `dynamic_bundle_storages`
   - `QueryIterationCursor::init_empty`: Duplicated from `init`
- `QueryIterationCursor::peek_last`: Thanks Giooschi (also added
internal unsafe blocks)
   - `tests::drop_ptr`: Moved safety comment out to the doc string
 
This lint would also apply to `missing_errors_doc`, `missing_panics_doc`
and `unnecessary_safety_doc` if we chose to enable any of those at some
point, although there is an open
[issue](https://github.com/rust-lang/rust-clippy/issues/13074) to
separate these options.
