Unreviewed, fix internal Cocoa builds after 262488@main

Rename `LookalikeCharacters::Observer` -> `LookalikeCharactersObserver` and move it out of the
`LookalikeCharacters` class namespace, so that it can be forward-declared (and we therefore don't
need to include `NetworkConnectionIntegrityHelpers.h` in `WebPageProxy.h`).

* Source/WebKit/Platform/cocoa/NetworkConnectionIntegrityHelpers.h:
(WebKit::LookalikeCharactersObserver::LookalikeCharactersObserver):
(WebKit::LookalikeCharactersObserver::create):
(WebKit::LookalikeCharactersObserver::invokeCallback):
(WebKit::LookalikeCharacters::cachedStrings const):
(WebKit::LookalikeCharacters::Observer::Observer): Deleted.
(WebKit::LookalikeCharacters::Observer::create): Deleted.
(WebKit::LookalikeCharacters::Observer::invokeCallback): Deleted.
* Source/WebKit/UIProcess/API/Cocoa/_WKWebAuthenticationPanel.mm:

Add a missing include for `Logging.h`.

* Source/WebKit/UIProcess/WebPageProxy.cpp:

Move the `NetworkConnectionIntegrityHelpers.h` include to the source file, and also add a missing
include for `WebCore/LookalikeCharactersSanitizationData.h`, which probably wasn't needed before due
to source unification.

* Source/WebKit/UIProcess/WebPageProxy.h:
