gen_rust_project: optimize aquery with many targets (#2941)

Hi, if I'm not mistaken, in Bazel `deps(a)+deps(b)` is equivalent to
`deps(a+b)`. The latter is more efficient because it doesn't have to
deduplicate common dependencies between a and b. This performance issue
has been triggered in our configuration, as we track roughly 700 targets
and 1600 transitive dependencies in our monorepo.
Running `aquery` with the original implementation takes 15 seconds on my
machine while the implementation proposed in this PR takes 1.5 seconds.
