This reverts commit b3230a3594.
Reason for revert: Possibly the cause of b/154581087

This change is to prevent misuse of window context from app
and leads to performance drop on system by limit the numer of window
context an app can use. Code snippet below is a sample to cause
this issue:
```
Rect getBounds() {
Context windowContext = context.createWindowContext(...);
return windowContext.getSystemService(WindowManager.class)
.getCuttentWindowMetrics().getBounds()
}
```
This method could be invoked dozens of times and produce dozens of window
tokens. It would slow down the speed of window traversalling. These
token won't be removed until system server has been GC'd.

An earlier CL with benchmarks has shown that sending strings as UTF-8
is 50% faster for US-ASCII strings, and still 68% faster for complex
strings referencing higher Unicode planes. (So an improvement in
both cases!)
Since code across the OS still makes heavy assumptions about Parcel
strings typically being UTF-16, we need to carefully migrate
Parcelables by hand, which is what this CLs begins doing.
This is a purely mechanical refactoring with no functional changes.

This was originally omitted because the only known case this
branch was hit was after a package update, which would inherently
change the code paths for the package.
Thus, spending the time to calculate these oldPaths was worthless
because they would never be applicable.
Seemingly this case where the paths are not changed has been
found, causing duplicate paths to be added to the same ClassLoader.
This warrants further investigation to determine why, but for now,
this should be safe to commit to fix the issue.

Test: manual used steps at b/149410951#comment57, verified that
paths were not added multiple times; device functions as normal
otherwise

The method will be used in AnrTests to check if the system can support ANR Dialog or not.

Test: atest NotificationManagerTest (with CTS cl)
Test: manual - have test app on "all" setting
- get a bubble
- hit "unbubble" from notification
=> no longer bubble
- get update to that notif, it shouldn't bubble

Changes to allow CTS test to control organized task so we can have the
tests run the same way sys-ui is driving things now. Control is given
back to sys-ui once the test is done running.

Bug: 152451909
Unit tests often execute server code in the context if a test process.
Such a process does not have the same permissions as formal system
processes. In particular, such a process does not have permission to
invalidate binder caches.
This change disables all binder cache code in the current process.
This means caching is disabled and invalidation never occurs. There
are no permission violations and the test process is also unable to
affect (through cache invalidation) the actual system processes.
Test: Ran a list of atests. Two had security violations before the
change but were okay after the change:
* FrameworksServicesTests
* UserSystemPackageInstallerTest
Ran additional tests to verify no regressions:
* PlatformScenarioTests
* PtsChreTestCases
* BluetoothInstrumentationTests
* UserLifecycleTests

Don't let process configuration change application configuration,
but allow to update non-default display configuration while
initialize since the context is focus on different display.

AutoCorker addresses the situation where big invalidation storms kill
performance but we don't have a way to insert a manual cork around
these update storms.
