  [iOS] run keyboard scrolling animations at a higher frame rate when possible

Reviewed by Simon Fraser.

In 273122 at main we opted into higher frame rate animations when performed by Core Animation on
qualifying hardware. We now do the same with scrolling animations resulting from interacting
with the keyboard (such as pressing the space bar) by setting similar properties on the
`CADisplayLink` created by `WKKeyboardScrollingAnimator`. Because we now have two different
places where we opt into a higher frame rate, we distinguish between the two cases by using
a different `CAHighFrameRateReason` value.

* Source/WebCore/PAL/pal/spi/cocoa/QuartzCoreSPI.h:
* Source/WebKit/Platform/cocoa/CAFrameRateRangeUtilities.h: Added.
(WebKit::highFrameRateRange):
* Source/WebKit/UIProcess/ios/WKKeyboardScrollingAnimator.mm:
(-[WKKeyboardScrollingAnimator startDisplayLinkIfNeeded]):
* Source/WebKit/WebKit.xcodeproj/project.pbxproj:
* Source/WebKit/WebProcess/WebPage/RemoteLayerTree/PlatformCAAnimationRemote.mm:
(WebKit::createAnimation):
(highFrameRateRange): Deleted.
