Vulkan: switch to Vulkan 1.3 and use dynamic rendering

[xen2]

PR Details

Moves the Vulkan backend to Vulkan 1.3 core:

• Require Vulkan 1.3: clear error at device creation otherwise. Excludes almost nothing in practice: timeline semaphores already made 1.2 the effective floor, and Android drivers jumped from 1.1 straight to 1.3.
  Note that we could have emulated timeline semaphore on 1.1 using https://github.com/KhronosGroup/Vulkan-ExtensionLayer but we're talking about pre-2022 devices. Let's drop support and if some game/user really need such old devices for a large scale game, we could reconsider.
• Dynamic rendering: vkCmdBeginRendering replaces render pass objects, deleting the VkRenderPass/VkFramebuffer machinery. Pipelines only declare attachment formats, and the render pass instance now stays open across pipeline changes. Also unblocks the upcoming explicit resource transition work.
• Aggregate feature structs (VkPhysicalDeviceVulkan11/12/13Features) instead of many individual structs.
• vkQueueSubmit2: simpler submits, and fixes wait stage masks that were too weak.

Net ~200 lines removed.
