This option provides an easy way to identify tests having no regression data
for sanity checks

* use OPENCV_TEMP_PATH environment variable on all platforms
* fix cleanup after OpenCV tests on Windows
* add --list flag to output names of all tests found
* do not override user-passed --perf_min_samples and --perf_force_samples
  options by --check flag
* fix complier checks inside run.py
