f4f3c15c1e render/vulkan: always wait for last stage to complete before rendering 
When we have multiple command buffers in flight, we need to make
sure we don't start rendering before the previous texture uploads
are complete.

f1eae0eeeb render/vulkan: add a command buffer pool 
Before re-using a VkCommandBuffer, we need to wait for its
operations to complete. Right now we unconditionally wait for
rendering to complete in vulkan_end(), however we have plans to
fix this [1]. To fully avoid blocking, we need to handle multiple
command buffers in flight at the same time (e.g. for multi-output,
or for rendering followed by texture uploads).

Implement a pool of command buffers. When we need to render, we
pick a command buffer from the pool which has completed its
operations. If we don't find one, try to allocate a new command
buffer. If we don't have slots in the pool anymore, block like we
did before.

a8a194d695 render/vulkan: switch to timeline semaphores 
Up until now we were using a VkFence for GPU-to-CPU
synchronization. This has some limitations that become a blocker
when trying to have multiple command buffers in flight at once
(e.g. for multi-output). It's desirable to implement a command
buffer pool [1], but VkFence cannot be used to track command buffer
completion for individual subpasses.

Let's just switch to timeline semaphores [2], which fix this issue,
make synchronization a lot more ergonomic and are a core Vulkan 1.2
feature.

f92d1499cd render/vulkan: add helper to load command function pointer 
If NULL is returned by vkGetDeviceProcAddr(), either the driver
is buggy, either the wlroots code is buggy. For a valid device and
command name, drivers are not allowed to return NULL per the spec.

This mirrors what the GLES2 renderer does in load_gl_proc().

270914d379 render/vulkan: add some interfaces to allow compositors to integrate 
Added wlr_vk_renderer_get_* functions to allow get the VkInstance,
VkPhysicalDevice, VkDevice, queue family of a wlr_vk_renderer.

Added wlr_vk_renderer_get_current_image_attribs function to allow get
the VkImage of current renderer buffer to use on compositors.

Added wlr_renderer_is_vk function, it's like the wlr_renderer_is_gles2,
returns true if the wlr_renderer is a wlr_vk_renderer.

Added wlr_vk_image_get_attribs function to get a VkImage and it's
extras information (e.g. a VkImageLayout and VkImageFormat of the
VkImage) from a wlr_texture.

cfb768aab9 render/vulkan: use struct initializers

7f5180af77 render/vulkan: simplify extension checks 
find_extensions() is clunky to use when checking only a single
extension, and it's surprising that it returns NULL on success.

Simplify by replacing it with a check_extension() function which
just checks whether a single extension is in the list.

render/vulkan: fix memory type detection 
From a comment by emersion:

> There is a logic error here: we pass 0xFFFFFFFF to vulkan_find_mem_type, which
> returns an index, and then we logical-and that with mem_reqs.memoryTypeBits.
> Instead we should pass mem_reqs.memoryTypeBits to vulkan_find_mem_type and use
> the result for the memoryTypeIndex field directly. Ideally checking for errors
> (-1 return value) in case no memory type is suitable.

98cf38601f render: replace wlr_texture_write_pixels with update_from_buffer 
This lets the renderer handle the wlr_buffer directly, just like it
does in texture_from_buffer. This also allows the renderer to batch
the rectangle updates, and update more than the damage region if
desirable (e.g. too many rects), so can be more efficient.

29291cb47c render/texture: drop wlr_texture_is_opaque 
Whether a texture is opaque or not doesn't depend on the renderer
at all, it just depends on the source buffer. Instead of forcing
all renderers to implement wlr_texture_impl.is_opaque, let's move
this in common code and use the wlr_buffer format to know whether
a texture will be opaque.

35d1bcff6f render/vulkan/pixel_format: do not leak props->... 
`vulkan_format_props_query` calls `query_modifier_support` which
initializes fields of `props` with allocated memory. this memory is
leaked if `query_modifier_support` does not find a supported format
and shmtex is not supported, as in this case `add_fmt_props` ends
up being false and the allocated fields of `props` are never freed.

The above output was based on just shoving it in ShaderPlayground -- I was not able to use pipeline feedback as I was unable to get RenderDoc working due to the EXT_physical_device_drm requirement.

I additionally considered using >> 1 instead of * 0.5, but AMD has dedicated modifiers to merge a * 0.5, * 2.0, etc in a single instruction. (Albeit, not taken advantage of in the code above, but might with ACO)

8e34692250 render/vulkan: add Vulkan renderer 
This new renderer is implemented with the existing wlr_renderer API
(which is known to be sub-optimal for some operations). It's not
used by default, but users can opt-in by setting WLR_RENDERER=vulkan.

The renderer depends on VK_EXT_image_drm_format_modifier and
VK_EXT_physical_device_drm.
