"*" means any representable value for the parameter (including valid
values, invalid values, and `NULL`).

The returned function pointer must: only be called with a dispatchable
object (the first parameter) that is pname:instance or a child of
pname:instance, e.g. slink:VkInstance, slink:VkPhysicalDevice,
slink:VkDevice, slink:VkQueue, or slink:VkCommandBuffer.

An "`available device extension`" is a device extension supported by any
physical device enumerated by pname:instance.
