Convert all tests to use TIMED_TEST_SUITE_INITIALIZE/CLEANUP

- Replace TEST_SUITE_INITIALIZE/CLEANUP with TIMED_ versions in 91 test files
- Add c_pal/timed_test_suite.h to 62 PCH files and 36 int/perf test files
- Add c_pal_reals and c_pal to ADDITIONAL_LIBS in test CMakeLists.txt
- Add process_watchdog reals (real_process_watchdog.c/.h) for both win32 and linux
- timed_test_suite.h uses real_ renames so the watchdog works even when
  interlocked and other dependencies are mocked in unit tests
