  [iOS] Replace a couple of UIScrollView SPI usages with API equivalents
https://bugs.webkit.org/show_bug.cgi?id=259223

Reviewed by Aditya Keerthi.

Remove two uses of SPI and IPI, which are trivially implementable using API instead. See below for
more details.

* Source/WebKit/Platform/spi/ios/UIKitSPI.h:
* Source/WebKit/UIProcess/API/ios/WKWebViewIOS.mm:
(-[WKWebView _zoomToFocusRect:selectionRect:fontSize:minimumScale:maximumScale:allowScaling:forceScroll:]):

Instead of relying on `-_effectiveContentInset`, just use the equivalent `-adjustedContentInset`.

* Source/WebKit/UIProcess/ios/WKScrollView.mm:
(-[WKScrollView initWithFrame:]):

Instead of calling `-_setIndicatorInsetAdjustmentBehavior:` with `.always`, simply set
`automaticallyAdjustsScrollIndicatorInsets` to `YES`.
