Update IoPerfCollection to use UidStatsCollector.

- IoPerfCollection process performance data and reports them to
bugreport. Update this class to use UidStatsCollector instead of
directly using process or I/O stats collectors.
- Remove the logic to resolve package/service name from UID because this
is already done by UidStatsCollector.
- Refactor internal structs to cache user package stats for both I/O and
proc stats. This makes easier to extend IoPerfCollection to process and
report (to bugreport) memory and CPU stats in the future.
- Update ProcStats struct field names to be similar to that of
IoPerfCollection.

Native (C++) code format is required to be compatible with .clang-format file. Run

git clang-format --style=file --extension='h,cpp,cc' HEAD~

Note that clang-format is not desirable for Android java files. Therefore the command line above is limited to specific extensions.
