[tests] Prepare objective-c tests for conversion to the new direct testing format

Browse Source 
Summary:
Rename symbols in test files so they are not duplicated and files can be analyzed together without affecting analysis results.
Fix some compilation errors, where files could be analyzed but would fail direct compilation.
Add Makefile mimicking the same analysis parameters used for the existing tests.
