[Sanitizers][Darwin][ASanABI] Fix architecture config for ASan Abi

Moved setting supported architecture to parent cmake configuration files
so they can be read by both lib and test CMakeList.txt.

Fixed issue with check-asan-abi that did not filter for current host architecture
which caused x86_64 bots to run Arm64 tests.

Added x86_64 as a supported arch to the test cmake file.
