Add LightsRequest.Builder#setLight back to SystemApi as Deprecated.

LightRequest.Builder#setLight was renamed to
LightRequest.Builder#addLight, as metalava check enforce the check for a
getter. ApiChecker CTS test still check the method with API 28, 29, 30 and will fail on:
 missing_method: android.hardware.lights.LightsRequest.Builder#setLight(android.hardware.lights.Light, android.hardware.lights.LightState)  Error: No method with correct signature found.
Add the method back to SystemApi and annotate it as deprecated.

Bug: 181019981
Test: atest android.signature.cts.api.system.SignatureTest#testSignature
