Subject: A test api to override carrier information

This API should only be used for testing purpose e.g., CTS/GTS/SL4A
By overriding carrier information, we could force a particular carrier id,
carrier's config, but also any country or carrier overlays to be loaded
when using a test SIM with a call box.

Bug: 72332597
Test: atest CtsTelephonyTestCases:CarrierIdentificationTest

Change-Id: Icd5804375ef9334c9f6c382cc6a774b9c9c15213
(cherry picked from commit 5b509b81a0d5b14148745368b153dc6b8d4482ac)
Merged-in: 5b509b81a0d5b14148745368b153dc6b8d4482ac
