[Rust] Revise list of default types (#4118)

* [Rust] Add some common std types

VecDeque, BTreeSet, HashSet

* [Rust] Move std types and traits to variables

* [Rust] Somewhat sort std types & traits

Some items were duplicated, not in the correct set and single lines are
generally hard to edit.

Try to establish a categorization into related types and traits without
thinking too much about it.

* [Rust] Rename `std_{types,traits}` to `prelude_*`

Reorganizing them in the process based on the modules they are defined
in.

Also split off enum names into a separate variable, although I don't
have a scope idea for them now.

Adds FromIterator, TryFrom, TryInto from the 2021 prelude.

Adds multiple types of std::sync and std::ops because they are used
frequently.

* [Rust] Complete list of std::collections
