The code did not follow the provided clang-format file, which causes
conflict when a developer runs clang-format on the repo. This commit fixes
the generator so that the output is what clang-format would generate.
One issue is that clang-format's ColumnLimit will wrap long lines, and is
very difficult to replicate in python code without excessive changes. The
chosen solution is to use a custom clang-format file for the Utilities
folder which ignores the ColumnLimit.
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.
