Reviewed by Antoine Quint.

The incoming IOSurface can't reliably be used for bounds calculation. It first
has to be turned back into a MTLTexture.

* Source/WebCore/Modules/webxr/WebXROpaqueFramebuffer.cpp:
(WebCore::WebXROpaqueFramebuffer::startFrame): Move the logic to test for the size
of the incoming texture until after we've associated the IOSurface with a MTLTexture.
(WebCore::WebXROpaqueFramebuffer::setupFramebuffer):
* Source/WebCore/platform/graphics/cocoa/GraphicsContextGLCocoa.h:
* Source/WebCore/platform/graphics/cocoa/GraphicsContextGLCocoa.mm:
(WebCore::GraphicsContextGLCocoa::attachIOSurfaceToSharedTexture): Return the width
and height of the texture along with the EGL image handle.
