[WebGPU] webgpu:api,operation,resource_init,texture_zero:* does not pass

Reviewed by Tadeu Zagallo.

Textures are not cleared by default and we don't want to incur
the cost of clearing them on creation, so track if they are loaded
or copied prior to being cleared and clear if needed.

Also resolve ambiguitiy that 'discard' on a render target should
clear the render target, which does not seem obvious, but per
gpuweb/gpuweb#4398 is intentional.
