UIWKDocumentRequestSpatialAndCurrentSelection should limit context to the editable root of the current selection
https://bugs.webkit.org/show_bug.cgi?id=235595
rdar://87835602

Reviewed by Aditya Keerthi.

Source/WebKit:

Adjust the behavior of document editing context requests in the case where the `SpatialAndCurrentSelection` flag
is specified, but no explicit `textInputContext` has been given. Instead of using the hit-tested corners of the
spatial request as-is, clamp to the visible start and end positions of the current editable root (only if it
exists).

This adjustment makes this particular request configuration useful for text input clients that just want to
request text input context information for the current editable element in a given rect, but don't already have
a text input element identifier.

Test: DocumentEditingContext.SpatialAndCurrentSelectionRequest_LimitContextToEditableRoot

* Platform/spi/ios/UIKitSPI.h:

Drive-by fix: also clean up a couple of old staging declarations.

* WebProcess/WebPage/ios/WebPageIOS.mm:
(WebKit::WebPage::requestDocumentEditingContext):

Tools:

Add a new API test to exercise the change.
