FindGTest: Allow either "Debug" or "Release" configurations.

Browse Source 
Call select_library_configurations on GTest library variable basenames "GTEST"
and "GTEST_MAIN" before passing ${basename}_LIBRARY variables to
find_package_handle_standard_args.  This allows either _DEBUG or _RELEASE
library variants to be found for find_package() to pass, whereas the original
version would require the presence of _RELEASE variants.

Fixes: #17799
