perf tools: Add PMU event JSON files for ARM Cortex-A76 and, Neoverse N1.

The source of the event codes and description text was the Neoverse N1
technical reference manual at:

  http://infocenter.arm.com/help/topic/com.arm.doc.100616_0301_01_en/neoverse_n1_trm_100616_0301_01_en.pdf

The Cortex-A76 shares the same event IDs as the Neoverse N1 and they
can be viewed at:
