volk for bazel

# You can use volk in header-only fashion. Include volk.h wherever you want to use Vulkan functions. In exactly one source file, define VOLK_IMPLEMENTATION before including volk.h. Do not build volk.c at all in this case. This method of integrating volk makes it possible to set the platform defines mentioned above with arbitrary (preprocessor) logic in your code.
