Main Vulkan context, allocated as AVHWDeviceContext.hwctx.
All of these can be set before init to change what the context uses

Queue family index to use for transfer operations, and the amount of queues enabled.
In case there is no dedicated transfer queue, nb_tx_queues must be 0 and queue_family_tx_index must be the same as either the graphics queue or the compute queue, if available.

| int AVVulkanDeviceContext::queue_family_comp_index |
Queue family index for compute ops, and the amount of queues enabled.
In case there are no dedicated compute queues, nb_comp_queues must be 0 and its queue family index must be set to the graphics queue.

| const char* const * AVVulkanDeviceContext::enabled_inst_extensions |
Enabled instance extensions.
If supplying your own device context, set this to an array of strings, with each entry containing the specified Vulkan extension string to enable. Duplicates are possible and accepted. If no extensions are enabled, set these fields to NULL, and 0 respectively.

| const char* const * AVVulkanDeviceContext::enabled_dev_extensions |
Enabled device extensions.
By default, VK_KHR_external_memory_fd, VK_EXT_external_memory_dma_buf, VK_EXT_image_drm_format_modifier, VK_KHR_external_semaphore_fd and VK_EXT_external_memory_host are enabled if found. If supplying your own device context, these fields takes the same format as the above fields, with the same conditions that duplicates are possible and accepted, and that NULL and 0 respectively means no extensions are enabled.

| VkPhysicalDeviceFeatures2 AVVulkanDeviceContext::device_features |
This structure should be set to the set of features that present and enabled during device creation.
When a device is created by FFmpeg, it will default to enabling all that are present of the shaderImageGatherExtended, fragmentStoresAndAtomics, shaderInt64 and vertexPipelineStoresAndAtomics features.
