simpleperf: support JIT/interpreted java code in system wide profiling.

It contains below changes:
1. Support monitoring multiple processes in JITDebugReader.
2. Switch from 100ms period to 100ms interval when scanning JIT debug
info changes.
3. Limit read entry length by seqlock different instead of a fixed
value.
4. Support disable/enable periodic events in IOEventLoop.
5. Remove duplicated dex file offsets in DexFileDso.
6. Enable JITDebugReader for recording on Android P.
7. Remove " (deleted)" suffix in filenames of maps, because some vdex
files in map file have this suffix.

Bug: http://b/79118393
Test: run `simpleperf record -a` manually.
Test: run simpleperf_unit_test.
