[macOS] Scrollbar corners fail to render with UI-side compositing
https://bugs.webkit.org/show_bug.cgi?id=248763
rdar://102906463
Reviewed by Simon Fraser.
Painting scrollbar corners is broken due to the lack of a platform context in
the web process. To fix, delegate drawing to the GPU process by using
`drawSystemImage` and introducing new `SystemImage` subclasses.
Scrollbar corners are currently drawn using AppKit and CoreUI.
`AppKitControlSystemImage` is introduced to provide a generic method of
rendering native controls, encapsulating the desired color scheme and tint
color. `ScrollbarTrackCornerSystemImageMac` is the concrete subclass
responsible for drawing the native control. Additional subclasses will be added
in subsequent patches, to support other controls that are drawn using CoreUI
options (progress bars and datalist dropdown buttons).
