vkGetPhysicalDeviceCalibrateableTimeDomainsEXT is instance-dispatchable function

[Janeczko Jakub]

TracyVk queries for vkGetPhysicalDeviceCalibrateableTimeDomainsEXT using vkGetDeviceProcAddr, but it is physical-device-level function.
As such the vkGetDeviceProcAddr will return NULL.

To fix this issue You should just query for vkGetPhysicalDeviceCalibrateableTimeDomainsEXT using vkGetInstanceProcAddr

Note that it may still be usefull to query vkGetCalibratedTimestampsEXT from device as it is a device-level function.
