Add new SF backdoor option: hdr/sdr ratio overlay
- follow how RefreshRateOverlay did in general.
- 1043 as new opcode to enable hdr/sdr ratio overlay.
- decouple SevenSegmentDrawer and SurfaceControlHandle helper classes
from RefreshRateOverlay.
- add corresponding SF backdoor test for validation.
- for non-HDR-supported device, we don't reject them to use SF backdoor
but 1.00 will be always shown on the screen if enabling.
Test: adb shell call service call SurfaceFlinger 1043 1; atest
SurfaceFlinger_test
