vkdevice: fine grained vulkan video extensions detection

Browse Source 
The Vulkan Video extensions can be available, according to the specification,
since Vulkan 1.1, but with other extensions dependencies. That's why this patch
adds a field in the extension structure, which represents the extension
dependency that the specified extension requires. And they are specified by
Vulkan Video extensions.

This allow to have a single function to check if the extension can be enabled
both by optional extensions and video extensions.

Regardless that video extension can be loaded since Vulkan 1.1, they are rather
loaded since Vulkan 1.3, when synchronization2 was promoted, so it isn't
checked as video_queue dependency.

Finally, this patch checks for each guard symbol.
