The mnemonic I use for transitions is "For this resource, all the commands before this may continue to src_access in src_stage and no commands after this proceed past dst_access in dst_stage.". I believe the src accesses here are right. You are waiting for any commands before this blit that write, transfer, specify this resource as color attachment as to finish. But, you are going to be using this as a blit source (I believe these are "transfers" in Vulkan parlance). So commands that read or transfer from it must wait.

Oh, poop. Sorry, its the other way round. What I said was TextureToBuffer.

Needed to update the dst access and stage to incude transfer.

Remove todo? There's no longer an ifdef.

Work towards flutter/flutter#123468
In order to support the usage of BufferView, I generalized the tracked buffer type from DeviceBuffer to Buffer. Should be mostly safe!
I confirmed that this runs correctly under moltenvk but I'm uncertain if there are additional ways to validate.
