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

Current per-API level task profiles replace the latest task profiles
rather than overriding the diffs. This poses an issue when a new
feature is added which is applicable to older devices as well we
have to change all per-API level profiles. Change the per-API task
profile support to load the latest task profiles first and then override
with per-API task profiles, similar to how vendor task profiles override
system task profiles. This minimizes the changes we need to do to the
per-API level task profiles going forward and is more consistent with
how vendor task profiles work.

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.

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

Kernel will batch the merge operations only when
block numbers of source and cow device are contiguous.
Daemon will read the COW file and post-process
the operations so that kernel can batch merge the potential
operations.
There are two key changes done in post-processing:
1: COW file contains all the copy operations at the
beginning of the file. We cannot allow batch
merging of COPY operations as a crash in between
the overlapping copies can result in a corrupted state.
Hence, allow copying individual blocks at a time.
2: Replace and Zero operations can be batch merged.
However, reading our existing COW format as-is
will not allow kernel to batch merge. Hence,
process the operations in such a way that kernel can batch
merge them.
Furthermore, it is observed that sync() after every
merge is a overhead. Hence, we will only sync()
for copy operations only. For replace and zero
operations, we will not explicitly sync. This is ok as
crash in between replace/zero merge operations can
redo those operations. However for copy, we have
to make sure that sync is completed before next copy
operation is initiated.
Merge time of a full OTA on bramble is around ~60
seconds as compared to ~10+ minutes prior to this
optimization.
Note that we still have copy operations which are not
batch merged. Hence, OTA with significant number of
copy operations can still have overhead on merge timings.

Refact cow_snapuserd unit test. This will
test code changes in daemon in isolation. Currently it tests
1: Reading snapshot device and validate data
2: Merge and validate data.
More tests related to merge will be added later; but this
should provide a baseline unit test for daemon.

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.
