b01aa99408 Revert "libprocessgroup: move freezer to uid/pid hierarchy" 
This reverts commit 1414a0d4d8.

Reason for revert: reversions of CLs from http://b/174776875 removed dependencies for this CL, and made the freezer non-functional. This CL has to be reverted as well

4d45b59f80 libprocessgroup: uid/pid hierarchy for cgroup v2 
Enable the uid/pid hierarchy for all groups when using cgroup v2. Mount
the hierarchy under the cgroup v2 root. Make sure that all files under
the hierarchy are accessible by the system user.

Test: booted the device, tested the freezer cgroup, manually verified
the working of the freezer from logs and by checking statuses of
processes.

Bug: 168907513
Test: Booted the device, verified no regressions on process group access

98a61dd583 Move rootdir/*.json to libprocessgroup 
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.

Test: builds
