MAINTAINERS: add "RUST [RUST-ANALYZER]" entry

This entry will handle the support for `rust-analyzer`, which at the
moment is essentially about the `scripts/generate_rust_analyzer.py`
script.

It is one more subentry of the Rust subsystem. The new branch is
already part of linux-next and will be used to send PRs to be merged
into rust-next.

Tamir and Jesung will take care of it. They have both been active around
the `rust-analyzer` support for a while.
