chore(tests): add code coverage for all targets

[nan-li]

Description

One Line Summary

Use Xcode's built in code coverage reporting, and add all 10 SDK frameworks for analysis.

Details

• Add all frameworks to check code coverage for (there are 10).
• Reminder there are 2 test plans that can be run, and coverage needs to be specified for each one:
  • UnitTestApp_TestPlan_Reduced (default plan in CI)
  • UnitTestApp_TestPlan_Full (default plan in Xcode)

Motivation

Increase testing and monitor code coverage for tests.

Scope

Testing only for code coverage

Testing

Unit testing

No new tests added
Badge test is flaky, causing tests fail.

Manual testing

Ran UnitTestApp_TestPlan_Reduced test plan and UnitTestApp_TestPlan_Full test plan with coverage.

UnitTestApp_TestPlan_Reduced

UnitTestApp_TestPlan_Full
