Keep it for external users in order to not cause breakages.
Also improve the other headers a bit while just at it.

This is possible because the lifetime of these structures coincide.
It has the advantage of allowing to remove AVHWFramesInternal
from the public header; given that AVHWFramesInternal.priv is no more,
most accesses to AVHWFramesInternal are no more; indeed, the only
field accessed of it outside of hwcontext.c is the internal frame pool,
making this commit very simple.

This is possible because the lifetime of both coincide.
Besides reducing the number of allocations this also simplifies
access to VulkanFramesPriv as one no longer has to
go through AVHWFramesInternal.

Without ff_vk_exec_discard_deps which is called by ff_vk_exec_wait,
the reference count of hwframe context cannot reach zero due to
circular reference created by ff_vk_exec_add_dep_frame.

win32 typically doesn't have unistd.h, so always including it will break
MSVC builds. The usage of those POSIX functions are already guarded by
_WIN32, so use that to guard unistd.h include as well.
VK_KHR_PORTABILITY_ENUMERATION_EXTENSION_NAME is required on macOS,

When users zero-init'd the struct, or left it as-is, the encode
queue family matched the graphics queue family, which led it to be
incorrectly logged as being used for encode.
This just improves the logging so this isn't printed anymore.
Fixes multiplane support on Nvidia.
Also, remove the ENCODE usage, even if the driver signals it as supported.
Currently, it's not used, and when it is used, it'll be gated behind
two extension checks.
The alignment in vulkan_unmap_from_drm() (formerly the clone
of vulkan_frame_free()) is nicer than the in vulkan_frame_free(),
let's preserve it.

The AVBuffer API uses uint8_t as base type for buffers
and therefore its free callbacks need to abide by this.
Therefore vulkan_frame_free() used an inappropriate signature
which caused casts whenever this function has been called
manually.
This commit changes this by making vulkan_frame_free()
use the proper type and a vulkan_frame_free_cb() that
is used as free callback for the AVBuffer API.

Currently, create_pnext is only used if an applicable external memory
extension is enabled. This will usually the case when used from the command
line, but may not be when the Vulkan context is created manually.
For images used in video decoding, create_pnext contains the video profile
list, which is mandatory.[1] This fixes a GPU crash when using RADV.

^~~~~~~~~~~~~~~~~
Today, cuda is not able to import multiplane images, and cuda requires
images to be imported whether you trying to import to cuda or export
from cuda (in the later case, the image is imported and then copied
into on the cuda side). So any interop between cuda and vulkan requires
that multiplane be disabled.
The existing option for this is not sufficient, because when deriving
devices it is not possible to specify any options.
And, it is necessary to derive the Vulkan device, because any pipeline
that involves uploading from cuda to vulkan and then back to cuda must
use the same cuda context on both sides, and the only way to propagate
the cuda context all the way through is to derive the device at each
stage.
ie:
-vf hwupload=derive_device=vulkan,<filters>,hwupload=derive_device=cuda
The temporary AVFrame on staack enables us to use the common
dependency/dispatch code in prepare_frame().
The prepare_frame() function is used for both frame initialization
and frame import/export queue family transfer operations.
In the former case, no AVFrame exists yet, so, as this is purely
libavutil code, we create a temporary frame on stack. Otherwise,
we'd need to allocate multiple frames somewhere, one for each
possible command buffer dispatch.
The idea was that it's faster to map linear images and copy them
via regular memcpy. This is a very niche use, plus very inconsistently
useful, as it would only really be faster on a few Intel GPUs.
Even then, using the non-cached memcpy would've been better.
Instead, scrap this code. Drivers are better at figuring out
what copy to use, and if we're host-mapping, it should actually be
just as fast, if not faster.
This commit adds proper handling of multiplane images throughout
all of the hwcontext code. To avoid breakage of individual
components, the change is performed as a single commit.
The hack was added to enable exporting of vulkan images to DRM.
On Intel hardware, specifically for DRM images, all planes must be
allocated next to each other, due to hardware limitation, so the hack
used a single large allocation and suballocated all planes from it.
By natively supporting multiplane images, the driver is what decides
the layout, so exporting just works.
It's a hack because it conflicted heavily with image allocation, and
with the whole ecosystem in general, before multiplane images were
supported, which just made it redundant.
This is also the commit which broke the hwcontext hardest and prompted
the entire rewrite in the first place.
