Remove if(DEBUG) around ProtoLogs for TV PiP code

When the logs were switched to ProtoLogs the if(DEBUG) statements to
prevent spamming the logs were kept, however they are not needed since
the ProtoLogs can be turned on and off on demand (off by default)

Bug: 218457585
Test: manual - enable logs (adb shell wm logging enable-text
WM_SHELL_PICTURE_IN_PICTURE) and all logs should be present
