iOS does not have a local inspector, only remote. So give it a custom
implementation separate from the WebKit/mac WebInspectorClient
implementation which handles an attaching/detaching local inspector.

* WebKit.xcodeproj/project.pbxproj:
* ios/WebCoreSupport/WebInspectorClientIOS.mm: Added.

Source/WebKit/mac:

The actual implementation at the WebCoreSupport/WebInspectorClient level
is the same as INSPECTOR_SERVER. Give debuggable pages a pageIdentifer.
