simpleperf: Add ETMDecoder.

It contains below changes:
1. Add ETMDecoder, which uses OpenCSD library to decode etm data.
2. Fix trace ids in AuxTraceInfoRecord to match those in etm data.
3. Dump build ids for all binaries in record cmd, to find them in
   etm decoding.
4. Add options in dump cmd to dump etm data.
5. Add a test line in dump cmd test to check that instruction range
elements are decoded and dumped.

Bug: 135204414
Test: run simpleperf_unit_test.
