Vulkan: Allow more than one atomic counter buffer binding dEQP assumes there are more than one atomic counter buffers available. This is technically not a requirement by the standard, but nevertheless could be what applications expect as well. This change adds support for multiple atomic counter buffer bindings. This is done by declaring an array of storage buffers for the atomic counter buffers (instead of declaring only one) and passing the (binding, offset) pair around to functions instead of just the offset. The atomic counter is found by indexing `binding` into the storage buffer array first before indexing `offset` into its `uint[]`. ProgramVk's default uniform collection is also fixed not to include atomic counter uniforms. A remaining issue is that atomic counter buffer offsets don't have alignment requirements in GLES, but Vulkan does for storage buffers. Similar to emulated transform feedback buffer offsets, these should be sent to the shader through uniform values. This will be done in a follow up change.
