[chromium] Build webkit with enable_web_intents set to 0.
https://bugs.webkit.org/show_bug.cgi?id=108408

Reviewed by Tony Chang.

I'll then make chromium build fine with that, then switch
enable_web_intents to 0, roll that into webkit, and then
actually remove the code hidden behind this flag.

Source/WebCore:

* bindings/v8/custom/V8IntentCustom.cpp:

Source/WebKit/chromium:

The features.gypi bit depends on https://codereview.chromium.org/12143002/
and will disable web intents support on android. Since common.gypi
sets enable_web_intents to 0 explicitly, it seems this is currently on
by accident anyway.

While it looks like this CL just removes ENABLE_WEB_INTENTS=1 from
features.gypi completely, it's still set further down the file if
enable_web_intents is on.

* WebKit.gyp:
* features.gypi:
* src/WebFrameImpl.cpp:
