This commit makes the documentation of `BTreeSet::drain_filter` more
consistent with that of `BTreeMap::drain_filter` after the changes in
f0b8166.

In particular, this explicitly documents the iteration order.

At least one of these is already in-tree; it seems plausible that
others might appear too.

Use diagnostic items instead of lang items for rfc2229 migrations

This PR removes the `Send`, `UnwindSafe` and `RefUnwindSafe` lang items introduced in rust-lang#84730, and uses diagnostic items instead to check for `Send`, `UnwindSafe` and `RefUnwindSafe` traits for RFC2229 migrations.

Update BTreeSet::drain_filter documentation

…items, r=jyn514

Document rustdoc with `--document-private-items`

The `tool_doc` macro introduced in rust-lang#86737 did not use `false` as the default value for `binary` when it is not provided, so the `if` is not even expanded and thus the argument is never provided if the `binary` argument isn't.

Resolves rust-lang#86900
