Issue Description

Although Carthage support has been removed there is a lot of legacy code still in the repo. Carthage supports dynamic frameworks meaning we would have to recompile these dependencies. This can lead to longer build times and significant increases in indexing. We can simply swap them out for their SPM counterparts.

• [x] Use OCMock static xcframework
• [x] Use facebook-ios-sdk SPM
• [x] Use Bolts SPM
• [x] Use Bolts Swift SPM
• [x] Use Starstream SPM
• [x] Remove git submodules
• [x] Remove Cartfile
• [x] Remove Scripts/build_third_party.rb
• [x] Remove any unnecessary .xcodeproj references
• [x] Remove Carthage install from CI
