Set Metal texture usage to allow texture copy via view.

MVKCmdCopyImage uses texture view if formats different. Enable
MTLTextureUsagePixelFormatView for VK_IMAGE_USAGE_TRANSFER_SRC_BIT.
Refactor mvkMTLTextureUsageFromVkImageUsageFlags() to clarify Metal usages
and enable views on depth-stencil attachments by default.
