recovery: Add screensaver mode. While it's waiting for user input, dim or turn off the backlight to avoid OLED burn-in. The backlight brightness will be reduced after the first timeout (default 120s), and then turned off after the second. Pressing any key will take it back to the normal brightness. While the display is off, the first key input will only turn on the backlight. The most common case that triggers the screensaver is under text mode, such as waiting for menu selection or viewing recovery logs. This CL doesn't change the brightness while it's installing updates or performing wipes under UI mode. When it encounters any install error under UI mode (user builds): - If it's NOT USB connected, it will reboot automatically after the first timeout (same as before); - If it's USB connected, it will dim and turn off the display per the change in this CL. Bug: 34077703 Test: Boot a device with the new recovery image. Wait for timeout. Change-Id: I0c14907e60340a7f037adb6e464942d099ada08b

recovery-persist executables exist only on systems without /cache partition. And we need to follow special steps to run tests for them.
Execute the test on an A/B device first. The test should fail but it will log some contents to pmsg.
Reboot the device immediately and run the test again. The test should save the contents of pmsg buffer into /data/misc/recovery/inject.txt. Test will pass if this file has expected contents.
ResourceTest validates whether the png files are qualified as background text image under recovery.
1. `adb sync data` to make sure the test-dir has the images to test. 2. The test will automatically pickup and verify all `_text.png` files in the test dir.
