>+        Add support for "TakeFindStringFromSelection" on iOS. Unlike macOS, iOS does not have a notion of a "find
>+        pasteboard" like macOS; instead, we handle this editing command by sending the selection string to the UI
>+        process, where it is exposed via WebKit SPI so that clients that present find-in-page UI (i.e. MobileSafari) are
>+        able to trigger find-in-page with this string.

>+        * UIProcess/API/Cocoa/WKWebView.mm:
>+        (-[WKWebView _takeFindStringFromSelection:]):
>+
>+        Provides a way to set the find string on iOS and macOS (an aside: takeFindStringFromSelection: already exists on
>+        macOS, but there is no equivalent protocol method on iOS, so this new SPI acts as a cross-platform way for
>+        WebKit clients to take the find string from the selection across all Cocoa platforms).

>+        (+[WKWebView _setStringForFindInPage:]):
>+
>+        Call into find-in-page helper functions.
>+
>+        (-[WKWebView _findString:options:maxCount:]):
>+
>+        On iOS, additionally update the find-in-page string when exercising the _findString:options:maxCount: SPI. This
>+        mirrors macOS behavior of updating the find pasteboard every time the find string changes; however, on macOS,
>+        this is implemented by the platform (in AppKit), whereas there's no platform find pasteboard on iOS, let alone
>+        logic to update it in UIKit. As such, we directly drive updates to the find string within WebKit.
>+
>+        * UIProcess/API/Cocoa/WKWebViewPrivate.h:
>+
>+        Add some new cross-platform find-in-page SPI. See above for more details.

>+        iOS, this instead returns the current global find string.
>+
>+        (WebKit::updateStringForFindInPage):
>+
>+        Sets the global find string. Uses the find pasteboard on macOS, and sets the global find string on iOS.
