Plug-ins have no way to find out when the device scale factor changes

https://bugs.webkit.org/show_bug.cgi?id=67226

Reviewed by Sam Weinig.

Source/WebKit2:

* PluginProcess/PluginControllerProxy.cpp:
(WebKit::PluginControllerProxy::geometryDidChange):
* PluginProcess/PluginControllerProxy.h:
This now takes the contentsScaleFactor and calls contentsScaleFactorChanged on its plug-in
if the scale factor changes.

* PluginProcess/PluginControllerProxy.messages.in:
GeometryDidChange now takes a contents scale factor parameter.

* WebProcess/Plugins/Netscape/NetscapePlugin.h:
* WebProcess/Plugins/Netscape/mac/NetscapePluginMac.mm:
(WebKit::NetscapePlugin::contentsScaleFactorChanged):
Implement contentsScaleFactorChanged and call NPP_SetValue with the new scale factor.

* WebProcess/Plugins/PDF/BuiltInPDFView.cpp:
(WebKit::BuiltInPDFView::contentsScaleFactorChanged):
* WebProcess/Plugins/PDF/BuiltInPDFView.h:
Add stub.

* WebProcess/Plugins/Plugin.h:
Add pure virtual contentsScaleFactorChanged member function.

* WebProcess/Plugins/PluginProxy.cpp:
(WebKit::PluginProxy::geometryDidChange):
Add geometryDidChange overload that doesn't take any parameters. Make it send over the
new scale factor to the plug-in process.

(WebKit::PluginProxy::contentsScaleFactorChanged):
Call geometryDidChange.

* WebProcess/Plugins/PluginView.cpp:
(WebKit::PluginView::setDeviceScaleFactor):
Call Plugin::contentsScaleFactorChanged.

* WebProcess/WebPage/WebPage.cpp:
(WebKit::WebPage::setDeviceScaleFactor):
Call setDeviceScaleFactor on all registered plug-ins.

Tools:

Keep a cached copy of the contents scale and update it when it changes.

* DumpRenderTree/TestNetscapePlugIn/Tests/mac/ContentsScaleFactor.cpp:
(ContentsScaleFactor::ContentsScaleFactor):
(ContentsScaleFactor::cachedContentsScaleFactor):
(ContentsScaleFactor::ScriptableObject::hasProperty):
(ContentsScaleFactor::ScriptableObject::getProperty):
(ContentsScaleFactor::NPP_New):
(ContentsScaleFactor::NPP_SetValue):

LayoutTests:

Update test to check that the scale factor is updated correctly.

* platform/mac-wk2/plugins/contents-scale-factor.html:
