Fixes the vk_layer_dispatch_table.h header file so that they can be used in other projects. The contents of this header and vk_dispatch_table_helper.h have been moved into a new header vul_dispatch_table.h. The structs VulDeviceDispatchTable and VulInstanceDispatchTable struct contain function pointers for the device and instance, respectively. The functions vul_init_device_dispatch_table and vul_init_instance_dispatch_table fill out the aforementioned structs, making the task of setting up the disptach table in a layer much simpler.
