simpleperf: Add JITDebugReader.

When profiling an app on Android >= P, simpleperf reads new JIT/dex
symfiles exported by the app's __jit_debug_descriptor and
__dex_debug_descriptor every 100ms. It also saves new JIT symfiles
in temporary files for unwinding/symbolization later. This is a
preparation to support profiling JITed/interpreted Java code.

Bug: http://b/73127105
Test: run simpleperf_unit_test.
Test: run simpleperf manually.
