Add a WKWebView input delegate SPI
https://bugs.webkit.org/show_bug.cgi?id=149646

Reviewed by Dan Bernstein.

Renames the existing _WKFormDelegate to _WKInputDelegate and adds a new delegate SPI method
-[_WKInputDelegate _webView:focusShouldStartInputSession:] that allows clients to allow or
disallow showing up the keyboard. To make this decision, clients are given a
_WKFocusedElementInfo, which contains information about the focused element prior to the
keyboard showing up so the client will be able to override default assistance behavior.

While the information contained in a _WKFocusedElementInfo currently seems like overkill for
_webView:focusShouldStartInputSession, our intentions are to give WebKit clients control over more
details of how node assistance works, such as being able to use a custom editor for certain
types of nodes.

* Shared/API/Cocoa/WebKitPrivate.h: Added new header _WKFocusedElementInfo.h.
* UIProcess/API/Cocoa/WKWebView.h:
* UIProcess/API/Cocoa/WKWebView.mm:
(-[WKWebView _inputDelegate]):
(-[WKWebView _formDelegate]):
(-[WKWebView _setInputDelegate:]):
(-[WKWebView _setFormDelegate:]):
(-[WKWebView initWithFrame:configuration:]): Deleted canAssistOnProgrammaticFocus flag.
(-[WKWebView canAssistOnProgrammaticFocus]): Ditto.
(-[WKWebView setCanAssistOnProgrammaticFocus:]): Ditto.
* UIProcess/API/Cocoa/WKWebViewConfiguration.h:
* UIProcess/API/Cocoa/WKWebViewConfiguration.mm:
(-[WKWebViewConfiguration init]): Deleted.
(-[WKWebViewConfiguration _canAssistOnProgrammaticFocus]): Deleted canAssistOnProgrammaticFocus flag.
(-[WKWebViewConfiguration _setCanAssistOnProgrammaticFocus:]): Ditto.
* UIProcess/API/Cocoa/WKWebViewPrivate.h:
* UIProcess/API/Cocoa/_WKFocusedElementInfo.h: Added.
* UIProcess/API/Cocoa/_WKFormDelegate.h:
* UIProcess/API/Cocoa/_WKInputDelegate.h: Copied from Source/WebKit2/UIProcess/API/Cocoa/_WKFormDelegate.h.
* UIProcess/ios/WKContentViewInteraction.mm:
(-[WKFocusedElementInfo initWithAssistedNodeInformation:isInteracting:]):
(-[WKFocusedElementInfo type]):
(-[WKFocusedElementInfo value]):
(-[WKFocusedElementInfo isUserInitiated]):
(-[WKContentView accessoryAutoFill]):
(-[WKContentView _startAssistingNode:userIsInteracting:blurPreviousNode:userObject:]): If the input delegate responds to
    shouldStartInputSession, consult it to see if we should bring up the keyboard; otherwise, use our default behavior.
