Enable hardware performance counter support for perf events. If

+ When the program accesses address 0, it will assert
automatically.
+ Hardware support is required, such as ARM V8M DWT
Review Comment:
You mean ARCH_HAVE_DEBUG not ARCH_HAVE_HWDEBUG, right? But ARMV7M also has
ARCH_HAVE_DEBUG and probably doesn't have this feature, correct? RISC-V also
have ARCH_HAVE_DEBUG
