The runtime is turning GENERAL layouts into FEEDBACK_LOOP ones when it
detects feedback loops in a render pass. This is breaking drivers that
would like to use a different HW layout for those 2 layouts because if
the application inserts barrier in the render pass, the barriers the
driver sees are inconsistent.
This could lead to barrier of this type :
- GENERAL -> FEEDBACK_LOOP (runtime)
- GENERAL -> GENERAL (app)
- FEEDBACK_LOOP -> GENERAL (runtime)

(cherry picked from commit 76cf391255)
Some tilers check for framebuffer local dependancy to determine if
they can rearrange or merge some sub-passes without breaking
their dependencies. Adding a helper for that.

This records any rendering pipeline flags in the render pass. This
provides much-needed information for the VK_KHR_fragment_shading_rate
and VK_EXT_fragment_density_map extensions as well as provides an
alternative to VkRenderingSelfDependencyInfoMESA which is based on
VK_EXT_attachment_feedback_loop_layout.
v2 (Connor): Name something more general
v3 (Faith): Also add the FSR flag

This has basically identical semantics to the pseudo-ext enum we were
using before. Also, now that it's in the actual Vulkan enum, we can get
rid of all the #pragma garbage to avoid compiler warnings.

Instead of making drivers dive into the render pass and framebuffer
themselves, provide a helper that constructs a VkRenderingInfo for a
render pass resume that they can use instead. This should reduce code
duplication between driver implementations of BeginRendering and
BeginCommandBuffer.

These helpers are used by vkCreateGraphicsPipelines to get the
VkPipelineRenderingCreateInfo and in vkCmdBeginCommandBuffer to get the
VkCommandBufferInheritanceRenderingInfo. This is required because the
Vulkan runtime code can't yet hook and modify calls made to driver-
provided functions. Instead, we just provide a helper to be used in leu
of vk_find_struct_const(). The structs themselves are stored in the
render pass so we can pass back a pointer and there's no need to
construct one on the stack or stuff it in the pipeline.

This implements vkCmdBeginRenderPass, vkCmdEndRenderPass, and
vkCmdNextSubpass in terms of the new vkCmdBegin/EndRendering included in
VK_KHR_dynamic_rendering and Vulkan 1.3. All subpass dependencies and
implicit layout transitions are turned into actual barriers. It does
require VK_KHR_synchronization2 because it always uses the 64-bit
version of the pipeline stage and access bitfields.
