  rdar://120053975 ([WebGPU] writeBuffer and writeTexture should use noCopy variants when creating temporary buffers (266821))

Reviewed by Tadeu Zagallo.

Some more complex demos can copy 300MB textures or buffers and copying
these is expensive and leads to OOM situations.

Establish a threshold, currently 32MB, where we use the no-copy variant
to avoid duplicating the memory. It requires us to submit the command buffer
immedietly, otherwise the memory may get deallocated too soon. That is the
trade off with the no-copy variants.
