Log Message:
-----------
Avoid using CanvasBase::allocateImageBuffer() in WebGL, WebGPU
transferToImageBuffer()

Reviewed by Mike Wyrzykowski.
The allocation function is related to how 2D context backing store is
allocated. transferToImageBuffer needs a general purpose ImageBuffer,
where the WebGL, WebGPU backing store is transferred to.
This makes it simpler to move 2D context related ImageBuffer code to
2D rendering context classes.

Example of failure being fixed here:
Previously transferToImageBitmap of a giant WebGL context failed due to
canvas area limitations.
