ETM device may not be ready when profcollectd is started.
So this CL adds interface to wait for ETM after boot:
1. In simpleperf_profcollect, split has_support() into
has_driver_support() and has_device_support().
2. In ProfcollectdBinderService and Scheduler, add interface
to register ProviderStatusCallback, which is called when
the trace provider is ready.
3. In profcollectd, register ProviderStatusCallback after boot.
Then record boot profile and schedule periodic recording in
the callback.

Test: on oriole EVT and DVT devices, profcollectd can record boot
Test: profile and periodic profiles.

For now, all the PGO enabled libraries are in these directories.
Filtering the profiles saves us some processing time.
We can add more paths if needed in the future.

Use the 2-space configuration by default and disable any formatting for
the demo/ subdirectory. The following command was used to generate this
change:
$ find . \( -name \*.cpp -o -name \*.h \) -exec clang-format \
--style=file -i {} \;
