Currently, tests for pKVM are written as hode-side tests which interact
with the platform using the `vm` tool. However, that approach has cause
many problems:
* Can't test Java APIs; we were testing the command line interface of
the tool actually.
* Unreliable connection to adb; we had to add busy loops to work around
some of the flakes.
We should move on to the device-side tests. There will be a
self-instrumened test apk which will be driven by tradefed.
However, one blocker to the plan is that the Java APIs are not available
to test apps, as we don't have a plan to make the APIs public in TM and
therefore we put the APIs behind signature-protected permissions
(com.android.MANAGE_VIRTUAL_MACHINE, com.android.DEBUG_VIRTUAL_MACHINE).
Since test apps can't be signed with the platform key, our test apk
can't have the permission.
This CL fixes the problem by turning on the `development` bit in the
protection level of the permissions. Then the permission can be granted
to the test apps satisfying following conditions (all):
* test app has `android:testOnly="true"` in its manifest. The flag
prevents the app from being uploaded to Play or installed from there.
* the app has to be installed with the "-t" (`INSTALL_ALLOW_TEST`) flag
* the permission has to be explicitly granted via `pm grant <package>
<perm>` command`.

Test: TARGET_BUILD_APPS="MicrodroidDemoApp" m apps_only dist
adb install --no-streaming -t out/dist/MicrodroidDemoApp.apk
adb shell
$ su; setenforce 0 // will be fixed
$ pm grant com.android.microdroid.demo
android.permission.MANAGE_VIRTUAL_MACHINE
run the demo app

This adds a simple integer addition service to the testapk's binary. The
demo app tries connecting the VM service once onPayloadReady is
triggered. Users can see the VM service's output.

Test: launch MicrodroidDemoApp
Test: atest MicrodroidHostTestCases

Because we'll now allow virtualizationservice permission only to
platform_apps.
Test: run demo app
