simpleperf: improve recording unwinding results. 1. Add MAP_MISSING result type. 2. Pass --log option to the simpleperf process running in app's context, in order to dump unwinding results when profiling android apps. Bug: http://b/69383534 Test: run simpleperf_unit_test.

simpleperf: report unwinding failures. 1. When --log debug is used, store unwinding results in UnwindingResultRecords in perf.data. 2. Use unwinding_result_reporter.py to report unwinding results. This is to help finding different unwinding failures. Bug: http://b/69383534 Test: run simpleperf_unit_test. Test: run unwinding_result_reporter.py manually.
