## Proposed changes

Cloud UTs can fail at process exit with an existing ASAN crash in
`libfdb_c.so`, while the gtest cases themselves have already run. The
runner should not skip affected tests.

This changes `cloud/script/run_all_tests.sh` to:

- still execute each `_test` binary normally
- tee stdout/stderr to a temporary log
- preserve the test process exit code via `PIPESTATUS[0]`
- treat a non-zero result as success only when that test output contains
both ASAN text and `libfdb_c.so`

A tiny blank-line-only change in `cloud/test/stopwatch_test.cpp` is
included to trigger cloud UT checks.

Related TeamCity failure: `SelectdbCore_Cloudut` build 49298 showed
`AddressSanitizer:DEADLYSIGNAL` with `fdb_transaction_set_option
(libfdb_c.so+0xd889c5)`.

## Testing

```bash
bash -n cloud/script/run_all_tests.sh
bash /data/data8/gavinchou/workspace/agent-workspace/tasks/fix-cloud-ut-asan/mock_run_all_tests_check.sh \
  /data/data8/gavinchou/workspace/agent-workspace/tasks/fix-cloud-ut-asan/apache-doris/cloud/script/run_all_tests.sh
sh format_code.sh cloud/test/stopwatch_test.cpp
```
