gsk: vulkan: rework image layout/access transitions

Browse Source 
By tracking the last transition we can build the appropriate barriers.
Also use the most appropriate initial layout/access at creation :

for linear image : predefined (we prepare the content ourself through memcpy)
for everything else : undefined (we don't care about the content, will most likely be erase)
