Adds additional captures for theming rust code.
I'm uncertain about whether `#` belongs in the `@operator` capture, but
I didn't see a more appropriate capture name in my brief hunt in other
files. It is the prefix of an `attribute_item`.. suggestions welcome.
Release Notes:
- Added `@operator`, `@lifetime` and `@punctuation.delimiter` captures
to Rust highlights file.
Question: I use type.super here because I made a similar change to the
ruby syntax to apply the same style to superclasses.
With this in mind, should this change be renamed to type.trait or should
it be renamed to something like type.italic so the ruby syntax or any
other language can all use type.italic? or maybe something else
altogether.

Release Notes:
- Exposed Rust traits as `type.interface` for individual syntax theming.
- Moves languages module from `zed` into a separate crate. That way we
have less of a long pole at the end of compilation.
- Removes moot dependencies on editor/picker. This is totally harmless
and might help in the future if we decide to decouple picker from
editor.
Before:
```
Number of crates that depend on 'picker' but not on 'editor': 1
Total number of crates that depend on 'picker': 13
Total number of crates that depend on 'editor': 30
```
After:
```
Number of crates that depend on 'picker' but not on 'editor': 5
Total number of crates that depend on 'picker': 12
Total number of crates that depend on 'editor': 26
```
The more crates depend on just picker but not editor, the better in that
case.
Release Notes:
- N/A
