CTest: more aggressive implementation of ctest_empty_binary_directory()
Make sure that CMakeCache.txt is the last file being removed since the binary directory may be left in a state that is no longer removable otherwise. Also retry removal a couple of times which makes this more robust on windows where file locks may temporarily prevent removal.
