simpleperf: replace config file with cmdline options.
1. For binary_cache_builder.py, annoate.py and pprof_proto_generator.py,
there are only a few options, use a config file seems overkill, so
replace them with cmdline options.
2. Add cmdline interface for app_profiler.py. It is to simplify usage,
and can be called from tests (will be added).
3. Simplify the way to find tools (including adb,readelf,addr2line),
try to find them in default install location of sdk and ndk. And output
error/warning msg if not found.
4. Raise exception in python are not always helpful for users to find
problems, because the error msg is hidden by exception stack dump. So
replace some log_fatal() with log_exit().
5. Change README.md accordingly.
