ee6e2ce149 arch/perf: add ARCH_HAVE_PERF_EVENTS to support hardware perf events
The implementation of up_perf_*() is in a different static library in nuttx:

Hardware: libarch.a
Software: libdrivers.a (weak function)

Since functions with weak attributes cannot be correctly replaced in multiple static libraries,
this PR will use macros to replace whether the arch supports hardware perf events
