Web Inspector: Canvas: support WebGPU content previews
https://bugs.webkit.org/show_bug.cgi?id=320702
Reviewed by Mike Wyrzykowski.
* Source/WebCore/html/canvas/CanvasRenderingContext.h:
* Source/WebCore/html/canvas/GPUCanvasContextCocoa.h:
* Source/WebCore/html/canvas/GPUCanvasContextCocoa.mm:
(WebCore::GPUCanvasContextCocoa::surfaceBufferToImageBuffer):
(WebCore::GPUCanvasContextCocoa::transferToImageBuffer):
(WebCore::GPUCanvasContextCocoa::configure):
(WebCore::GPUCanvasContextCocoa::present):
Track the last presented buffer so snapshots of WebGPU `<canvas>` read the
visible content without advancing the presentation buffer.
Clear the tracked content when it is transferred.
* Source/WebCore/inspector/InspectorCanvas.cpp:
(WebCore::InspectorCanvas::getContentAsDataURL):
Use the configured `<canvas>` for a `GPUDevice` when capturing a snapshot.
Reject `GPUDevice` configured for multiple `<canvas>` since
`Canvas.requestContent` only returns one image.
* Source/WebInspectorUI/UserInterface/Models/Canvas.js:
(WI.Canvas.supportsRequestContentForContextType): Deleted.
(WI.Canvas.prototype.requestContent):
* Source/WebInspectorUI/UserInterface/Views/CanvasContentView.js:
(WI.CanvasContentView.prototype._showError):
Remove the now-unnecessary support check since all `<canvas>` context types
support snapshotting.
* LayoutTests/inspector/canvas/requestContent-webgpu.html: Added.
* LayoutTests/inspector/canvas/requestContent-webgpu-expected.txt: Added.
