Combines loadVulkanLib, loadGetInstanceProcAddr and loadGlobalLevelFunctions( PFN_vkGetInstanceProcAddr )
from module erupted.functions. If this function succeeds the function vkGetInstanceProcAddr
from module erupted.functions can be used freely. Moreover the required functions to initialize a
vulkan instance a vkEnumerateInstanceExtensionProperties, vkEnumerateInstanceLayerProperties and vkCreateInstance
are available as well. To get all the other functions an vulkan instance must be created and with it
loadInstanceLevelFunctions be called from either erupted.functions or through a custom tailored module
with mixed in extensions through the erupted.platform.mixin_extensions mechanism.
Additional device based functions can then be loaded with loadDeviceLevelFunctions passing in the instance or
with creating a vulkan device beforehand and calling the same function with it.
Note: as this function indirectly calls loadVulkanLib loading the vulkan lib, freeVulkanLib should be called
at some point in the process to cleanly free / unload the lib
all errors during vulkan lib loading and vkGetInstanceProcAddr retrieving are reported to log_stream, default stderr
log_stream = file stream to receive error messages, default stderr
