tool_doswin: add debug envs to test filename sanitization failure modes

Browse source 
- `CURL_FN_SANITIZE_BAD=<any-value>` to simulate
  `SANITIZE_ERR_INVALID_PATH`.

- `CURL_FN_SANITIZE_OOM=<any-value>` to simulate
  `SANITIZE_ERR_OUT_OF_MEMORY`.

Both are Windows/MS-DOS-specific and require debug-enabled curl build.

Cherry-picked from #20116
Closes #20125
