[llvm-branch-commits] [compiler-rt] Cleanup use of COMPILER_RT_INCLUDE_TESTS (PR #98246)

https://github.com/MaskRay approved this pull request. I am not familiar with how the tests cmake work, but this patch indeed improves consistency. For example, `foreach(arch ${MEMPROF_TEST_ARCH})` is at the toplevel while its unittest `foreach` is guarded by `COMPILER_RT_INCLUDE_TESTS`.
