For NR (non-standalone), use LTE signal strength as primary rule

Browse Source 
There are two signal strengths, NR and LTE signal strength,
during NR (non-standalone). A lot of carriers' requirement define
UE show LTE signal strength on status bar during
NR (non-standalone).
Add a carrier config whether to use LTE signal strength as
primary during NR (non-standalone)

Bug: 152864241
Test: make pass.
