Skip all watchpoint hit-count/ignore-count tests for multithreaded API tests for now on arm64 Darwin. On AArch64, insns that trigger a WP are rolled back and we are notified. lldb needs to disable the WP, insn step, re-enable it, then report it to the user. lldb only does this full step action for the "selected thread", and so when a program stops with multiple threads hitting a stop reason, some of them watchpoints, any non-selected-thread will not be completed in this way. But all threads with the initial watchpoint exception will have their hit-count/ignore-counts updated. When we resume execution, the other threads sitting at the instruction will again execute & trigger the WP exceptoin again, repeating until we've gone through all of the threads. This bug is being tracked in llvm.org/pr49433 and inside apple in rdar://93863107
