Add PAL softlinking and SPI headers for frameworks that are required for the "network connection
integrity" feature.

* Source/WebKit/NetworkProcess/NetworkConnectionToWebProcess.cpp:
(WebKit::NetworkConnectionToWebProcess::requestLookalikeCharacterStrings):

Add an IPC method to asynchronously fetch a set of lookalike character strings.

* Source/WebKit/NetworkProcess/cocoa/NetworkConnectionIntegrityHelpers.mm: Added.

Add a helper file that contains the definition of `requestLookalikeCharacterStrings` (and any other
related helpers that are related to network connection integrity, which we'll require in subsequent
patches).
