[Bug]: GTEST_INTERNAL_HAS_COMPARE_LIB has a wrong condition for older Android NDK releases

[jpboivin]

Describe the issue

GTEST_INTERNAL_HAS_COMPARE_LIB is checking for __cpp_lib_three_way_comparison (okay) and GTEST_INTERNAL_HAS_INCLUDE(<compare>) && GTEST_INTERNAL_CPLUSPLUS_LANG >= 201907L. I think the later is trying to support early implementations of the three-way comparison, but it will fail on some (like the one that shipped with the Android NDK 24/25 release). That version of the NDK lacks the comparison operators needed by PrintTo. As it is a C++20 feature, I think it should only check for __cpp_lib_three_way_comparison (the feature test macro).

Here is the error:
