While analyzing gst_vulkan_get_or_create_image_view_with_info() it
seems obvious that this function returns NULL, and that this should be
covered in the return annotations. However, closer inspection indicates
that this is only a precondition check when the incoming arguments are
incompatible with each other, and should not be considered as a function
that optionally returns a pointer.
Signify this by using precondition checks instead of an opencoded
if-return-NULL.

Now that driver version is expected to be equal or superior to 1.3.275 the bug
in NVIDIA and RADV regarding usage is solved, we can revert commit b7ded81f7b.
Also this patch sets the internal usage variable after all the validation are
run, thus the state don't keep an invalid usage.
Finally, the now unused supported_usage variable is dropped.

Virtual method set_config() can be called several times, and if the number of
profiles counter isn't reset the pool will reach an error state.
The purpose of number of profiles is to check the number of valid vulkan video
profiles (two in the case of transcoding use-case, for example) so it's local to
set_config() virtual method.

This is to avoid a regression in validation layer (introduced by commit
916c4e70cd) when using vulkandownload
VUID-VkImageMemoryBarrier2-srcAccessMask-03914 .. vkCmdPipelineBarrier2():
pDependencyInfo->pImageMemoryBarriers[1].srcAccessMask (VK_ACCESS_TRANSFER_READ_BIT)
is not supported by stage mask (VK_PIPELINE_STAGE_2_VIDEO_DECODE_BIT_KHR)
since vulkandownload set DPB memories' access mask to
VK_ACCESS_TRANSFER_READ_BIT, while they are retain by the DPB queue, so when
they are used as DPB after been shown, this validation error is raised.
Must of the barrier values are set ignoring the previous state of the vulkan
images.

The access flags are kept around the operations, but when the buffer is
released, the access flag should be reset to its original value, since queue
transfers can be done along the pipeline and, when reusing the buffer, the new
queue might not support the latest access flag.

Instead of dragging the last destination pipeline stage as current barrier
source pipeline stage (which isn't a valid semantic) this patch adds a parameter
to gst_vulkan_operation_add_frame_barrier() to set the source pipeline stage to
define the barrier.
The previous logic brought problems particularly with queue transfers, when the
new queue doesn't support the stage set during a previous operation in a
different queue.
Now the operation API is closer to Vulkan semantics.

Define a default usage and use it instead of repeating the same bitwise
addition.
Therefore, when usage is defined as zero, the usage is defined with the
format's supported usage and the default usage, now without the storage
bit, but with color and input attachment bits.

With clang on macOS:
```
error: format specifies type 'long' but the argument has type 'uint64_t' (aka 'unsigned long long')
...
error: format specifies type 'unsigned long' but the argument has type 'VkImageView' (aka 'unsigned long long')

When building for iOS in Cerbero, as of MoltenVK SDK 1.3.283, we have
to statically link to libMoltenVK since it no longer ships a dylib.
This requires linking to libc++, so we find the dep with the objc++
compiler to ensure that meson uses the right linker.
