Move USE_COLORIZED_NOTIFICATIONS to com.android.

It's @hidden, but CTS needs it to be out of the android.*
namespace too.

Fixes: 64613274
Test: Grab the cts binaries(android-cts.zip) from OC Release
Test: Extract and from android-cts/tools directory, launch ./cts-tradefed
Test: On the DUT with CL cherrypicked, run the below(will run this test on both abi's):
Test: run cts -m CtsPermission2TestCases -t android.permission2.cts.PermissionPolicyTest#testPlatformPermissionPolicyUnaltered --skip-connectivity-check --skip-preconditions --serial <device serial>
Test: android.permission2.cts.PermissionPolicyTest#testPlatformPermissionPolicyUnaltered doesn't fail for android namespace:android.permission.TRIGGER_TIME_ZONE_RULES_CHECK
