Subject: [PATCH v3 0/7] Additional methods for Vec

This adds various Vec methods. Some of them are needed by Rust Binder,
and others are needed in other places. Each commit explains where it is
needed.

This series is based on top of alloc-next and rust: alloc: split
`Vec::set_len` into `Vec::{inc,dec}_len`
https://lore.kernel.org/rust-for-linux/20250416-vec-set-len-v4-0-112b222604cd@gmail.com/

Changes in v3:
- Rebase on split `Vec::set_len` into `Vec::{inc,dec}_len`.
- Various modifications to work with inc/dec_len instead of set_len,
  with some Reviewed-by's dropped due to this.
- Move push_within_capacity impl into an unchecked variant.
- Link to v2: https://lore.kernel.org/r/20250321-vec-methods-v2-0-6d9c8a4634cb@google.com

Changes in v2:
- Add two more methods that I needed.
- Introduce some uses of set_len.
- Add example to retain.
- Simplify pop.
- Adjust 11 to 10 in push_within_capacity example.
- Link to v1: https://lore.kernel.org/r/20250320-vec-methods-v1-0-7dff5cf25fe8@google.com
