Give the tests the ability to emulate other devices screens

Browse Source 
This code contains utility clases that can change the display
of a device and make it look like another device.
The function DisplayEmulator#emulate receives a DeviceEmulationData
a certain grid to emulate and a callback, everyting that happens
inside of the callback will happen when the device is being emulated
and can be used by other tests.

Example test:
package com.android.launcher3.deviceemulator;
import androidx.test.ext.junit.runners.AndroidJUnit4;
import androidx.test.filters.MediumTest;
import com.android.launcher3.deviceemulator.models.DeviceEmulationData;
import com.android.launcher3.ui.AbstractLauncherUiTest;
import org.junit.Test;
import org.junit.runner.RunWith;
import java.util.concurrent.TimeUnit;

@MediumTest
@RunWith(AndroidJUnit4.class)
public class TestTest extends AbstractLauncherUiTest {
    @Test
    public void testEmulation() throws Exception {
        String deviceCode = "pixel6pro";
        DeviceEmulationData deviceData = DeviceEmulationData.getDevice(deviceCode);
        String grid = "normal";
        DisplayEmulator displayEmulator = new DisplayEmulator(mTargetContext);

        displayEmulator.emulate(deviceData, grid, () ->{
            TimeUnit.SECONDS.sleep(10);
            return true;
        });
    }
}

Test: You could use the test above to make your device look like a
Pixel6 pro for 10 secons.
