vk: Re-name command buffer implementation files
Previously, the command buffer implementation was split between anv_cmd_buffer.c and anv_cmd_emit.c. However, this naming convention was confusing because none of the Vulkan entrypoints for anv_cmd_buffer were actually in anv_cmd_buffer.c. This changes it so that anv_cmd_buffer.c is what you think it is and the internals are in anv_batch_chain.c.
