When task profiles changes happen, devices released under older API
levels might have to use the same profiles as before. This might be
due to for missing kernel features or some other reasons. Add support
for per-API task profiles to accommodate this scenario. With this
mechanism when ro.product.first_api_level is non-empty, the system
looks for /system/etc/profiles/task_profiles_<api level>.json file
and uses it if it exists. If ro.product.first_api_level is not defined
or per-API task profiles file does not exist the system falls back to
the default /system/etc/profiles/task_profiles.json file.
As before, these task profiles can be competely overwritten using
/vendor/etc/task_profiles.json if needed.

Put tasks into a subgroup so that we can set things up e.g. soft cpu
bandwidth and/or uclamp.

remove cgroup v1 freezer entries from init.rc, add a new cgroup v2
controller and modify plists to properly interact with it.
Bug: 154548692
Test: manually verified the the cgroup v1 freezer controller isn't
created and a new controller for cgroup v2 is created under the correct
sysfs directory.

create new profiles to allowing thawing and freezing back the freezer
cgroup
Bug: 151225245
Test: Manually verified that using the SetTaskProfiles method on the
profiles thaws and freezes back the freezer cgroup.

task_profiles.json currently uses attributes of a defunct version of
uclamp, which was used for testing.
Let's use the attributes that actually got merged upstream instead.

To support setting multiple profiles with one call. The json format
is as below example.
"AggregateProfiles": [

{
"Name": "SCHED_SP_BACKGROUND",
"Profiles": [ "HighEnergySaving", "LowIoPriority", "TimerSlackHigh" ]
},
...
}

Also, removed test to strull and inline static constexpr variable.

- Add proto3 files as schema for JSON task profiles / cgroups
files.
- Add tests to ensure the JSON files (on the device) conforms
the schema. (libprocessgroup_proto_test)

They are installed to /system/etc, not /. Hence, move
out of rootdir/ and move into the code that parse these
files (i.e. libprocessgroup).
Also, Android.mk->bp.
