SWDEV-423672 - Always compile and install gtest

This commit makes sure GTest is always compiled with rocm_smi_lib_tests.

GTest installation was inconsistent outside of AMD CI environment.
libgtest.so wouldn't get installed with rocm_smi_lib_tests if gtest
existed on the build machine. Which is undesirable when packaging.
