Source/WebKit/chromium:

public/platform/WebMimeRegistry.h is a temporary forwarding header to ease the transition. Once downstream
callers are updated to the new location this header can be removed.

WebString, WebCString, and WebCommon.h will remain in place as forwarding headers for users of the WebKit client
API.

* WebKit.gyp:
* public/platform/WebCString.h:
* public/platform/WebCommon.h:
* public/platform/WebMimeRegistry.h:
* public/platform/WebString.h:

Tools:

Teaches the WEBKIT_EXPORT check about the chromium WebKit platform API header location.

* Scripts/webkitpy/style/checkers/cpp.py:
