If the application did not define one yet, define our own VK_DEFINE_NON_DISPATCHABLE_HANDLE that is independent of the architecture. Vulkan, by default, provides a define that depends on the architecture, which causes the symbol type to be different. This causes an architecture dependent .gir file, which then causes multilib installation problems because the .gir files can't be shared. Make it possible to override the format specifier and provide a default one that is compatible with the default non dispatchable handle. Return VK_NULL_HANDLE from functions that return a non-dispatchable handle. Fixes #1566 Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2130>
