UniformAndStorageBuffer8BitAccess capability. When using the 8-bit storage extension it basically always used the `UniformAndStorageBuffer8BitAccess` capability, even in cases where it wasn't required. For instance if we are targeting Vulkan 1.1 (SPIR-V 1.3 or higher), and we are only using 8-bit types in an SSBO, we only need the `StorageBuffer8BitAccess` capability. I fixed this by enabling storage buffer use in Vulkan 1.1 / SPIR-V 1.3 or higher, and then changing the logic to match. I also added some tests that will output different capabilities when run on Vulkan 1.0 and 1.1, thus they are added twice to the test list (one for each version). Fixes #1539
