Instead of this way, since data is marked as "spy_disable" can we just not generate the read intrinsic for this case?
We already handle other cases like this, so I think cutting out the read intrinsic for spy_disabled is probably a cleaner approach than a check like this.

Support sparse buffer in vkCmdCopyBuffer, vkCmdFillBuffer and
vkCmdCopyBufferToImage.
Support extract geometry data from sparse buffer
'Read' the memory of sparse buffers
Implement doVkCmdFillBuffer
Tested with all the samples we have.
