REGRESSION(307450@main): WebGL: Crash resizing canvas after losing WebGL
context due to many contexts
https://bugs.webkit.org/show_bug.cgi?id=309777
rdar://172265758
Reviewed by Dan Glastonbury.
Avoid accessing WebGLDefaultFramebuffer::size() when context is lost,
in didUpdateCanvasSizeProperties(), transferToImageBuffer().
Prior fix (webkit.org/b/309777, 308389@main, 673b8d7495af) applied to
lost contexts that did not destroy the underlying context.
