chore: Add .xcodeproj back in the framework.

[iHackSubhodip]

What's changing?

• Add .xcodeproj back in the framework.
• Add GoogleMaps.bundle in .xcodeproj copy bundle resources.
• Add GMUGeometryRendererTest, which was causing the below issue.
• Rename folder GoogleMapsUtilsSwiftTests to GoogleMapsUtilsTests

Why? (The issue)

• Google Maps SDK for iOS requires GoogleMaps.bundle to be part of your target under 'Copy Bundle Resources' (GMSServicesException)
• Root Cause: Currently, there is no .xcodeproj in the framework, and the GoogleMaps dependency is fetched from SPM, instead of xcodeproj's Copy Bundle Resources.
• Attaching screenshot for more reference.
• Reference PR: Link

Validation:

• I did run the Unit tests, it's passing.
