[rust] Add `rust_unit_tests_group(...)` gni template.
This CL adds a `rust_unit_tests_group(...)` gni template that can
generate a Chromium-bot-friendly script that can run _all_ Rust unit
tests inside the transitive `deps` of the group.
Manual testing:
1. Checking that the tests can be run locally:
$ ninja -C out/rust build/rust/tests
$ out/rust/bin/run_native_rust_unittests__from__build_rust_tests
... the tests execute successfully ...
2. Checking that the tests can be run on the bots in a follow-up CL:
https://crrev.com/c/3322199/6
3. Checking that the runtime_deps are reasonable:
$ gn clean out/rust
$ gn desc out/rust \
build/rust/tests:native_rust_unittests__from__build_rust_tests \
runtime_deps
bin/run_native_rust_unittests__from__build_rust_tests
