Move config_inflateSignalStrength to CC

Sim based customizations should not be resources because
of two reasons:
1. The MCC/MNC value in AssetManager for Dual sim devices is undefined
2. There is no support for MVNOs.

For dual sim devices there is only one value for MCC/MNC in
AssetManager and that value is updated from multiple places without
deciding if it should be the default voice sim card, the default
data sim card or whatnot.
  This means that when frameworks is trying to decide what resource
to use there is no guarantee that the resource that arrives is for
the particular subscription we are asking for.

MVNOs cannot be separated through only MCC/MNC but need more
parameters like service provider, imsi, GID1 etc. MVNO support
is available in CarrierConfig.

When we now have support for ADCP updates of customizations and
start using carrier id this is better placed in CarrierConfig,
we then get support for MVNOs at the same time.

Bug: 148483577
Test: Customize for sim card x and not for sim card y, insert both
sim cards in a dual sim device and see the difference.
