Move test discovery logic into new catch_discover_tests_impl method
and make CatchAddTests aware of whether it is being launched in
CMake's script mode.
When launched in script mode, catch_discover_tests_impl is called
passing arguments obtained from the definitions passed into the call
to cmake. This preserves the existing behavior assumed by Catch.cmake.
Looking ahead, it also allows CatchAddTests to be included in
generated files and call catch_discover_tests_impl to perform test
discovery at test runtime with the new PRE_TEST discovery mode
introduced later.
This enables setting the required PATH/LD_LIBRARY_PATH environment variables both when retrieving the list of text cases and when executing the tests.
