simpleperf: fix tests for dwarf callgraph unwinding.
32-bit simpleperf can't unwind a 64-bit `sleep` process in aarch64
environment. It makes following error in tests:
simpleperf is built in arch arm, and can't do stack unwinding for arch arm64
So make the workload be able to start a process
running callback function. By profiling that process, we can
guarantee that 32-bit simpleperf is profiling a 32-bit process.
Also fix a flaky test IOEventLoop.signal.
Build 32-bit simpleperf_unit_test on 64-bit devices.
Bug: http://b/33167911
Test: run simpleperf_unit_test.

simpleperf: support hotplug events in record cmd.
1. When a cpu is down, read records from event files on that cpu,
then close those event files.
2. When a cpu is up, open event files on that cpu, and create
mapped buffer for those event files to dump records.
3. Instead of creating a mapped buffer for each event type on each
cpu, we can just create a mapped buffer for all event types on
each cpu.
4. When new event files are created, store a EventIdRecord record in
perf.data to notify record_file_reader.cpp.
Bug: http://b/29245608
Test: run simpleperf record cmd and make cpu offline and online.
Test: run simpleperf_unit_test.

simpleperf: use libevent in record command.
Support read Event in IOEventLoop, test it, and use it
in record command.
Format related code and clean up some comments.
