libfscrypt: simplify fscrypt_policy_ensure()
fscrypt_policy_ensure() sets an encryption policy if the directory is
empty, otherwise it verifies the existing encryption policy.
However, it's unnecessary to actually implement this logic in userspace,
because this is the behavior of the FS_IOC_SET_ENCRYPTION_POLICY ioctl
already. See the documentation:
https://www.kernel.org/doc/html/latest/filesystems/fscrypt.html#setting-an-encryption-policy
Therefore, just call FS_IOC_SET_ENCRYPTION_POLICY and handle errors
appropriately.
This makes the code shorter and less racy, and it also fixes the issue
where if files were created in the directory before an encryption policy
is set, the error message was confusing:
Failed to get encryption policy for $dir: No data available
Now it's:
Failed to set encryption policy of $dir to ...: Directory not empty
Test: booted after factory reset, checked log, rebooted, checked log
again.

Add support for new taskstats v9 functionality
Kernel ABI for taskstats has been uptated to version 9.
Thrashing data is the base for PSI used by userspace lmk,
so good to expose here for debugging purposes.

Add new traces.
Updates included:
- Adding traces from a few games and one top app (Angry Birds2, Candy Crush,
Pubg, Google Photos).
- Change the dumps directory to traces to use a better name.
- Add new traces to TraceBenchmark.cpp.
- Add a TRACES file that includes information about how the trace files
were collected.
Test: Unit tests pass.
Test: Ran the trace benchmarks.

simpleperf: add AuxRecord and AUXTRACE feature section.
In the kernel, each time generating a block of etm data, it also
generates a PERF_RECORD_AUX record. An Aux record contains a timestamp
showing when a block of etm data is generated. It can be used to
synchronize etm data with other records (like mmap and comm records).
So we want to parse etm data each time seeing an Aux record (as in dump
cmd). It needs to know etm data locations in perf.data without reading
the whole file. To fulfill that, this CL also adds AUXTRACE feature section,
in the same format as in linux perf.
Also dump AUX records and their corresponding etm data in dump cmd.

Test: run simpleperf_unit_test.
Test: run `simpleperf record -e cs-etm xxx` && `perf report -D --stdio`.
