simpleperf: Use CallChainJoiner.
1. In record cmd, split most code in Run() into three functions to make it easier to maintain.
2. In record cmd, use CallChainJoiner by default when -g option is used. And allow using
--no-callchain-joiner option to disable the joiner, and --callchain-joiner-min-matching-nodes
to adjust the joiner.
3. Adjust the interface of UnwindCallChain() to return sps used by the joiner.
4. Add functions in SampleRecord to use callchains returned by the joiner.
Add CallChainRecord to keep callchains returned by the joiner for debugging.
5. In dump cmd, show callchains of SampleRecord and CallChainRecord for debugging.
Bug: http://b/69383534
Test: run simpleperf_unit_test.
Test: run python test.py.
