Move service worker registration matching for navigation loads to network process
https://bugs.webkit.org/show_bug.cgi?id=203144

Source/WebCore:

For regular loads, we no longer match service worker registration explicitly.
This is now done by NetworkResourceLoader explicitly.
We still need to explicitely match registrations in those two cases:
- There is an app cache resource that can be used. We will use it only if there is no registration.
- There is a resource from the meory cache that can be used. We will match the registration to make sure 
the document is controlled by the right service worker. The load will still be served from the memory cache.

Since DocumentLoader is no longer matching registration, we need a way from NetworkProcess to inform that there is 
a matching registration and that the document is controlled.
For that purpose, DocumentLoader is adding itself in a global map with the temporary document identifier as the key.
Adding to the map happens when loading the main resource and removal from the map happens when destroying the DocumentLoader.
For this to happen properly, the temporary document identifier is kept the same for the lifetime of the DocumentLoader.

Registration matching was postponed until service worker registration is done.
Since we no longer do registration matching in WebProcess, we need to wait in NetworkProcess for that to happen.
We introduce a way for SWServer to notify when import is completed for that purpose.

Covered by existing tests.

Source/WebKit:

Create a WebSWServerConnection whenever receiving a load request in NetworkProcess.
This connection is used to check for service worker registration in case of navigation loads.
Similarly, we create a WebSWClientConnection whenever WebProcess needs it, including when receiving WebSWClientConnection messages from NetworkProcess.
This for instance happens when service worker registration import is complete to fill the shared registration origin store.

Delay loads until SWServer has finished importing its registrations.
This is needed since we might otherwise not intercept loads that could be intercepted.
Waiting for importing registrations was previously ensured by WebProcess getting a matching registration in DocumentLoader.

NetworkResourceLoader is now checking for service worker interception in case of redirections for navigations.
This is needed as redirections could end up using a new registration.

Tools:

* TestWebKitAPI/Tests/WebKitCocoa/ServiceWorkerBasic.mm:
We are now creating a WebSWClientConnection whenever receiving a WebSWClientConnection message
from NetworkProcess. It is free to do so given it no longer requires sending some IPC.
Update the tests accordingly.
A future patch will remove the service worker registration bit feature and corresponding test.
