Consolidate export files and add testing exports for the libwebrtc project. This bug covers a few export-file-related issues: 1. Removes unused files: Source/ThirdParty/libwebrtc/Configurations/libwebrtc2.exp Source/ThirdParty/libwebrtc/Configurations/libwebrtc4.exp 2. Consolidates macOS, iOS and iOS Sim export files into a single file (since they all had the exact same list of symbols): Source/ThirdParty/libwebrtc/Configurations/libwebrtc.mac.exp Source/ThirdParty/libwebrtc/Configurations/libwebrtc.iOS.exp Source/ThirdParty/libwebrtc/Configurations/libwebrtc.iOSsim.exp Changed to: Source/ThirdParty/libwebrtc/Configurations/libwebrtc.exp 3. Introduces libwebrtc.testing.exp for exporting test symbols for Debug and Release builds. Source/ThirdParty/libwebrtc/Configurations/libwebrtc.testing.exp 4. Adds a "Generate Export Files" build phase script in the Xcode project to merge the files as needed.
