Reviewed by Youenn Fablet.

General clean-up of libwebrtc export files.  Adds the ability to
export symbols only for testing by introducing a build phase
script in Xcode.

* Source/ThirdParty/libwebrtc/Configurations/DebugRelease.xcconfig:
(WK_EXPORT_SYMBOLS_FOR_TESTING): Add.
- Setting this Xcode variable enables the symbols in
  libwebrtc.testing.exp to be exported when building Debug or
  Release configurations.

* Source/ThirdParty/libwebrtc/Configurations/libwebrtc.exp: Renamed from Source/ThirdParty/libwebrtc/Configurations/libwebrtc.mac.exp.
* Source/ThirdParty/libwebrtc/Configurations/libwebrtc.iOS.exp: Remove.
* Source/ThirdParty/libwebrtc/Configurations/libwebrtc.iOSsim.exp: Remove.
- The symbols in all three files were identical, so consolidated
  them into a single export file.

* Source/ThirdParty/libwebrtc/Configurations/libwebrtc.testing.exp: Add.
- List of symbols to export when testing.

* Source/ThirdParty/libwebrtc/Configurations/libwebrtc.xcconfig:
(EXPORTED_SYMBOLS_FILE):
- Update to point to generate export file created by "Generate
  Export Files" build phase script.

* Source/ThirdParty/libwebrtc/Configurations/libwebrtc2.exp: Remove.
* Source/ThirdParty/libwebrtc/Configurations/libwebrtc4.exp: Remove.
- Remove unused export symbol dumps.

* Source/ThirdParty/libwebrtc/libwebrtc.xcodeproj/project.pbxproj:
- Rename libwebrtc.mac.exp to libwebrtc.exp, and remove deleted
  files.
(Generate Export Files): Add.
- Add build phase script to generate libwebrtc export file.
