vkdecoder: handle barrier internally for coincide references

Browse source 
This is to avoid a regression in validation layer (introduced by commit
916c4e70cd) when using vulkandownload

VUID-VkImageMemoryBarrier2-srcAccessMask-03914 ..  vkCmdPipelineBarrier2():
pDependencyInfo->pImageMemoryBarriers[1].srcAccessMask (VK_ACCESS_TRANSFER_READ_BIT)
is not supported by stage mask (VK_PIPELINE_STAGE_2_VIDEO_DECODE_BIT_KHR)

since vulkandownload set DPB memories' access mask to
VK_ACCESS_TRANSFER_READ_BIT, while they are retain by the DPB queue, so when
they are used as DPB after been shown, this validation error is raised.

Must of the barrier values are set ignoring the previous state of the vulkan
images.
