Add lockscreen recently received BC Smartspace Targets to sysUI dumpSys.

Launcher dumpsys already has this information. However, in some
situations, Lockscreen targets are different from Launcher.

This may help with further debugging b/320376858.

Flag: NONE
Bug: 320376858
Test: adb shell dumpsys activity service com.android.systemui | grep "LockscreenSmartspaceController:" -B 2 -A 20
Test: `adb bugreport` and check the SysUi custom view contains the dumpsys
Change-Id: Ied1360dcfc17b2c44b53a58d8cb3d5ccdc6d61c9
