RFR: 8300806: Update googletest to v1.13.0 [v4]

[Mikael Vidstedt]

> Please review this PR which updates the required version of googletest to v1.13.0.
> 
> It’s been (quite) a while since we upgraded the version of googletest used to run the hotspot unit tests (test/hotspot/gtest). The current version (1.8.1) is from 2018 and there is build issue with Xcode 14.x which has been resolved in more recent versions of googletest.
> 
> The configure.ac file has been removed from googletest so the only file which contains the version is CMakeLists.txt, hence the removed logic from `make/autoconf/lib-tests.m4`.
> 
> Testing: tier1, gtest:all, GHA
