[Qt] Re-enable plugins on Mac.

https://bugs.webkit.org/show_bug.cgi?id=116622
Reviewed by Tor Arne Vestbø.

Source/WebCore:

* platform/FileSystem.h:
* platform/qt/FileSystemQt.cpp:
(WebCore::unloadModule):
  - Q_WS_* aren't defined since Qt5, use Q_OS_MACX instead.
* plugins/mac/PluginPackageMac.cpp:
(WebCore::PluginPackage::fetchInfo):
(WebCore::PluginPackage::load):
  - createCFString now does the adoption itself.
* plugins/mac/PluginViewMac.mm:
  - Add missing include.

Source/WebKit/qt:

* WebCoreSupport/ChromeClientQt.cpp:
(WebCore::ChromeClientQt::windowResizerRect):
  - Add missing parenthese.

Tools:

Plugins on Mac were only enabled if !embedded but the later was set if
QPA is enabled, which is the default since Qt 5.0.

Remove references to 'embedded' and fix various build issues,
PluginViewMac.mm and PluginPackageMac.cpp haven't been compiled since a few
months.
