Reviewed by Tim Horton.
Source/WebCore:
On iOS, the primary pointer will always be touch input, so the `hover`/`pointer` media query
should never change. If a mouse is connected, however, `any-hover`/`any-pointer` should
change as now there is at least one device that supports `hover`/`fine`. Note that in the
case of `any-pointer` this means that both `coarse` and `fine` will apply. Catalyst assumes
that there is always a mouse connected.

Refactor logic in `anyHoverEvaluate` and `anyPointerEvaluate` to move platform code into the
respective `WebKit::WebPage` file.

Use `BackBoardServices` to listen for mouse devices changes and notify all WebProcess.

(WebKit::WebProcessProxy::notifyHasMouseDeviceChanged): Added.
Tell the shared `WKMouseDeviceObserver` to start listening for mouse device changes when
creating the WebProcess so that the shared `WKMouseDeviceObserver` knows to notify all
instances when mouse devices change. Make `allProcesses` into a `private static` member
function so that it can also be used in `UIProcess/ios/WebProcessProxyIOS.mm`.

(WebKit::WebProcessPool::platformInitializeWebProcess):
Use the current state of the shared `WKMouseDeviceObserver` when creating WebProcess instead
of sending a `SetHasMouseDevice` message immediately after the WebProcess is created.
