[WebGPU] Calling GPUTexture.destroy() on the result of
GPUCanvasContext.getCurrentTexture() is problematic

Reviewed by Tadeu Zagallo.
Calling GPUTexture.destroy() on the result of
GPUCanvasContext.getCurrentTexture() was
problematic because we don't continuously make new IOSurface backed MTLTexture
instances
for the canvas.
We don't need to, we just need to ensure that calling destroy makes the Texture
act
like an invalid texture and that calling getCurrentTexture() returns a
non-destroyed
texture.
