perf mem: Trace physical address for Arm SPE events

Currently, Arm SPE events don't trace physical address, therefore, the
field 'phys_addr' is always zero in synthesized memory samples.  This
leads to perf c2c tool cannot locate the memory node for samples.

This patch enables configuration 'pa_enable' for Arm SPE events, so the
physical address packet can be traced, finally this can allow perf c2c
tool to locate properly for memory node.
