BUG: Fixed ASAN CI test discovery and leak detection (#1037)

* Fixed issue with catch2 test discovery for asan CI

* Catch2 runs the test executable in order to discover the tests
but the executable couldn't find the clang asan library in the build
step

* Added leak suppressions file for LeakSanitizer

* Ignore leaks detected in:
  * "/usr/bin" e.g. bash and python
  * "site-packages/" e.g. numpy
  * "pybind11.h"
    * Currently having an issue with leaking enum bindings
    * pybind/pybind11#3865
