simpleperf: add binary_cache_builder script.
To report on host, we need to pull binaries from device to host.
binary_cache_builder.py is used to pull needed binaries automatically.
Other changes:
Move common functions to utils.py.
Move libsimpleperf_report.so to proper directory, so we can add other
host shared libraries and target binaries in the future.
Bug: http://b/32834638
Test: run binary_cache_builder.py for N, O devices, both root and non-root.

simpleperf: improve script interface.
1. In ReportLib, return structure instead of pointer to structure.
So users can use 'sample' instead of 'sample[0]', as in report_sample.py.
2. For python3, convert char pointer to str type. Because str is more
convenient to use.
Bug: http://b/32834638
Test: run simpleperf_report_lib.py and report_sample.py.

Support to use kallsyms
Also:
- Adapt to use with Python 3
(where str is a wide type but our C API's expect 8 bit character strings)
- Use OS specific so names (e.g. simpleperf_report.dll on Windows)
- On Windows as we use mingw to build, preload libwinpthread-1.dll.
Test: with manual incovation using report_sample.py

Support for multiple instances
Allows to use separate instances for separate perf.datai
files (and possibly also separate instances on separate threads)
Test: Tested by running report_sample.py

simpleperf: add python report interface on linux.
1. Build libsimpleperf_report.so on host, which exports functions
to access samples.
2. Add simpleperf_report_lib.py to wrap libsimpleperf_report.so.
3. Write report_sample.py to test simpleperf_report_lib.py. The
output format of report_sample.py matches the need of building
FlameGraph.
Bug: http://b/31069528
Test: run report_sample.py on perf.data.
Test: run simpleperf_unit_test.
