This CL updates the ProcessCpuTracer.getName method to force a refresh
of the process name when the current state indicates that it was named
either 'usap32' or 'usap64'. This will prevent false attribution of
process statistics to system service processes.

In common cases, to resume the next activity we need to wait for the
current one to be paused. Since starting a process for activity is
asynchronous, if we already know the process of next activity has not
started yet, we can start the process earlier so the time waiting for
the pause to complete can be saved.
Also if the launching activity is going to be the top app, we can set
the top schedule group right after its process is started so the start
time before actually launching the activity can be improved.
Although before the current activity is paused, the next top activity
may still change and results some empty processes. That should not be
a common case and the process is still useful when going back the stack,
and the empty background processes are easier to be reclaimed.

Test: Launch calculator from launcher, the event log am_proc_start will
show "pre-top-activity".
Test: Cold launch a top activity, the system log should not show
"not expected top priority".
Test: Use startActivities to start serveral activities in a sequence.
Check "adb shell cat /proc/$pid/task/$pid/cgroup" for each process.
Only the last one has top-app, others are background.

loss of performance is tiny because, image will be resized at ImageUtil.isGrayscale() method.
Test: situation that one notification is sended to other resoltion devices, ex) using DEX mode,
Test: notification can be inflated at different resolution context.
Test: and app can have notification icon that is made dynamically.
Test: (it doesn't have resource for each resolution. ex: calendar notice icon with number)
Test: at this moment, judgement for grayscale can be differed from each device.

This commit allows the startLegacyVpn() call to start Platform VPN
profiles, allowing Settings to use the IKEv2/IPsec VPN options
When using an aliased private key, the
Ikev2VpnProfile.KEYSTORE_ALIAS_PREFIX must be prepended to the front of
the alias. This will in turn result in the fromVpnProfile() function to
pull the key from the KeyStore, as opposed to the inline-key that the
VpnManager API uses.

Update KernelSingleUidTimeReader to read BPF data rather than per-UID
proc files when the BPF data is available. This is implemented by
calling libtimeinstate functions via JNI.
Extend KernelSingleUidTimeReaderTest to exercise both the BPF and proc
file code paths.

Update KernelCpuUidTimeReader and its subclasses to support reading
frequency, active & cluster times from BPF maps rather than proc files
on devices that support this approach. BPF-based accounting offers
improved accuracy as it can detect every context switch, whereas the
proc files attribute a full tick period to whatever happens to be
running when the tick occurs.
Add a KernelCpuUidBpfMapReader class modeled on
KernelCpuProcStringReader, with singletons for reading each distinct
set of data. These follow the locking approach used by
KernelCpuProcStringReader to ensure thread safety, but they collect
data by calling libtimeinstate functions via JNI rather than reading
text from proc files. They also provide a getDataDimensions() function
to retrieve information currently provided by the header rows of the
proc files, such as the list of available freqs or the number of cores
on each cluster.
Extend the KernelCpu*TimeReaderTest classes to exercise the BPF path
for each reader class, and add a KernelCpuUidBpfMapReaderTest modeled
on KernelProcStringReaderTest.
Bug: 138317993
Test: KernelCpu*TimeReaderTests and KernelCpuUidBpfMapReaderTest pass
