Now that we have LocalCallingIdentity, we can start caching it in
very narrow cases. We must be careful to not cache too long, since
any changes to granted permissions for the UID mean we need to
re-evaluate any cached answers.
The best middle-ground for this in the Q release is to use an active
camera session as a proxy for when we should create a cache object
and then later invalidate it. (It's very unlikely that a user
changes permissions while actively using the camera, and this is
a strong signal that the caller is sensitive to performance.)
Many other sprinkled optimizations to avoid extra binder calls into
the OS, such as aggressively caching VolumeInfo related details.
Track IDs that are owned by each LocalCallingIdentity, to speed up
all future security checks.
Dispatch all change notifications asynchronously, and delay them by
several seconds while the camera is being actively used, to give
more important foreground work a fighting chance. Invalidate
thumbnails asynchronously.
Optimizations to ModernMediaScanner where it's safe to skip the
"reconcile" and "clean" steps when we're focused on a single file
that we successfully scanned.
Local tests show this CL improves performance of a test app that
takes 100 rapid shots by 45%. (All the collective optimizations
done so far this week add up to a 70% improvement.)

Currently only for the ContextImpl.enforcePermission code paths and only
when 'secure debug_package_permission_check' is set.
This feature is disabled on user-builds.

This CL makes it so that UIModeManager will not allow dark mode
to be changed prior to initial setup wizard being completed.
Additionally, it makes it so that when UIModeManager starts it
will try to start in light mode prior to setup wizard completing
regardless of what the backed up value is. We also register for
an observer if when we start UIModeManager we notice that setup
wizard has not run and defer updating dark mode to the true value
until we see that setup wizard completes.

Test: atest android.view.textclassifier
Test: (Performance) Test: frameworks/base/apct-tests/perftests/textclassifier/run.sh
Compare performance results with ConfigParser.ENABLE_DEVICE_CONFIG
set to true vs false. Trivial regression recorded i.e. 1.03x.
Test: (Manual) Change flags and see them reflected. e.g.
adb shell cmd device_config put textclassifier system_textclassifier_enabled false
Verify that app no longer uses the OEM TCS but the AOSP TC.

TimeController and QuotaController flags don't have to be changed
atomically with other JobScheduler constants, so it's best to have them
be separate. I think it's best to have the QuotaController constant
change be atomic, which is why the flag is set up as a key/value pair.

As per API feedback in b/126727563, move LOCATION_MODE_ON to SystemApi
instead of deprecated. This is safe as this constant is not used
anywhere yet.

(cherry picked from commit 7449108978)
- When MediaMetadataRetriever can't create the thumbnail of some
HEIF files, attempt decoding it from ExifInterface.
- ImageDecoder can't create the thumbnail with getThumbnailBytes
from ExifInterface in some cases. It will occur DecodeException:
Failed to create image decoder with message 'unimplemented'Input
contained an error. Attempt to decoding the full image in these
cases.
- Use orientation from ExifInterface to transform the thumbnail to
right orientation.
