Michael Bolin b68366718b ci: reuse Bazel CI startup for target-discovery queries (#19232)
## Why

A rerun of the Windows Bazel clippy job after
[#19161](https://github.com/openai/codex/pull/19161) had exactly the
cache behavior we wanted in BuildBuddy: zero action-cache misses. Even
so, the GitHub job still took a little over five minutes.

The problem was that the job was paying for two separate Bazel startup
paths:

1. a `bazel query` to discover extra lint targets
2. the real `bazel build --config=clippy ...` invocation

On Windows, that query was bypassing the CI Bazel wrapper, so it did not
reuse the same `--output_user_root`, CI config, or remote-cache setup as
the real build. In practice that meant the rerun could still cold-start
a separate Bazel server before the actual clippy build even began.

## What

- add `.github/scripts/run-bazel-query-ci.sh` to run CI-side Bazel
queries with the same startup and cache-related flags as the main Bazel
command
- switch `scripts/list-bazel-clippy-targets.sh` to use that helper for
manual `rust_test` target discovery
- switch `tools/argument-comment-lint/list-bazel-targets.sh` to use the
same helper
- simplify `.github/scripts/run-argument-comment-lint-bazel.sh` so its
Windows-only query path also goes through the shared helper

This keeps the target-discovery queries aligned with the later
build/test invocation instead of treating them as a separate cold Bazel
session.

## Verification

- `bash -n .github/scripts/run-bazel-query-ci.sh`
- `bash -n scripts/list-bazel-clippy-targets.sh`
- `bash -n tools/argument-comment-lint/list-bazel-targets.sh`
- `bash -n .github/scripts/run-argument-comment-lint-bazel.sh`
- mocked a Windows invocation of `run-bazel-query-ci.sh` and verified it
forwards `--output_user_root`, `--config=ci-windows`, the BuildBuddy
auth header, and the repository cache flags
