[Vulkan][TextureCache] Always use identity-swizzled views for storage images (#321)

Browse source 
Validation flagged writes to a VK_DESCRIPTOR_TYPE_STORAGE_IMAGE descriptor because the bound VkImageView had a non-identity component mapping  and hence the vuid-00336 error, this fixes the said error.

------

This commit helps to fix some graphical issues on games like Trident's Tale, where game didn't render anything than just plain terrain, helps to stabilize Nier Automata graphical issues, meanwhile the most annoying glitches are gone, there's still remain other issues.
