simpleperf: add inplace-sampler event type.
Add inplace-sampler event type, so it can be used in
record/list command. This cl doesn't add code for communicating
with profiled process, and fake records in InplaceSamplerClient.cpp
for testing purpose.
Refactor runtest.py to test inplace-sampler profiling.
Bug: http://b/30974760
Test: run runtest.py --inplace-sampler.

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.
