Source/WebInspectorUI: [Windows] Correct windows build. Get rid of unnecessary pre-build step. We don't build anything
in this project, just copy some files into the WebKit resource folder. This was fooling the
build system into thinking something failed, resulting in a build error.

* WebInspectorUI.vcxproj/WebInspectorUI.vcxproj: Remove reference to WebInspectorUIPreBuild.cmd
* WebInspectorUI.vcxproj/WebInspectorUI.vcxproj.filters:
* WebInspectorUI.vcxproj/WebInspectorUIPreBuild.cmd: Removed.

Source/WebKit: [Windows] Unreviewed build correction.
Update project dependencies so that build logs on machines will include output from the
WebInspectorUI project.

* WebKit.vcxproj/WebKit.sln:
