• Disable empty Cargo test targets (#21584)

  ## Summary
  
  `cargo test` has entails both running standard Rust tests and doctests.
  It turns out that the doctest discovery is fairly slow, and it's a cost
  you pay even for crates that don't include any doctests.
  
  This PR disables doctests with `doctest = false` for crates that lack
  any doctests.
  
  For the collection of crates below, this speeds up test execution by
  >4x.
  
  E.g., before this PR:
  
  ```
  Benchmark 1: cargo test     -p codex-utils-absolute-path     -p codex-utils-cache     -p codex-utils-cli     -p codex-utils-home-dir     -p codex-utils-output-truncation     -p codex-utils-path     -p codex-utils-string     -p codex-utils-template     -p codex-utils-elapsed     -p codex-utils-json-to-toml
    Time (mean ± σ):      1.849 s ±  4.455 s    [User: 0.752 s, System: 1.367 s]
    Range (min … max):    0.418 s … 14.529 s    10 runs
  ```
  
  And after:
  
  ```
  Benchmark 1: cargo test     -p codex-utils-absolute-path     -p codex-utils-cache     -p codex-utils-cli     -p codex-utils-home-dir     -p codex-utils-output-truncation     -p codex-utils-path     -p codex-utils-string     -p codex-utils-template     -p codex-utils-elapsed     -p codex-utils-json-to-toml
    Time (mean ± σ):     428.6 ms ±   6.9 ms    [User: 187.7 ms, System: 219.7 ms]
    Range (min … max):   418.0 ms … 436.8 ms    10 runs
  ```
  
  For a single crate, with >2x speedup, before:
  
  ```
  Benchmark 1: cargo test -p codex-utils-string
    Time (mean ± σ):     491.1 ms ±   9.0 ms    [User: 229.8 ms, System: 234.9 ms]
    Range (min … max):   480.9 ms … 512.0 ms    10 runs
  ```
  
  And after:
  
  ```
  Benchmark 1: cargo test -p codex-utils-string
    Time (mean ± σ):     213.9 ms ±   4.3 ms    [User: 112.8 ms, System: 84.0 ms]
    Range (min … max):   206.8 ms … 221.0 ms    13 runs
  ```
