simpleperf: add test for dumping regs for tracepoint events.

If the test fails, probably a kernel patch is missing:
5b09a094f2 arm64: perf: Fix callchain parse error with kernel tracepoint events

To support the test, also enable recording tracepoint events in
app's context.

Bug: http://b/29520177
Test: run CtsSimpleperfTestCases64 on devices.
