Temporary fix to prevent TEMPORARILY_NOT_METERED leak

Browse Source 
Currently we are seeing TEMPORARILY_NOT_METERED occurs on non-5G
devices. This fix adds more checks to prevent incorrect
TEMPORARILY_NOT_METERED being set. Before we root cause the issue,
we only allow this bit when all of the following conditions met.

1. Devices should support 5G.
2. Carriers should support 5G unmetered data.
3. Device should camp on 5G network.

This temporary fix should be removed after we root cause the issue.
