    * dnn: Add a Vulkan based backend
    
    This commit adds a new backend "DNN_BACKEND_VKCOM" and a
    new target "DNN_TARGET_VULKAN". VKCOM means vulkan based
    computation library.
    
    This backend uses Vulkan API and SPIR-V shaders to do
    the inference computation for layers. The layer types
    that implemented in DNN_BACKEND_VKCOM include:
    Conv, Concat, ReLU, LRN, PriorBox, Softmax, MaxPooling,
    AvePooling, Permute
    
    This is just a beginning work for Vulkan in OpenCV DNN,
    more layer types will be supported and performance
    tuning is on the way.

    * dnn/vulkan: Add FindVulkan.cmake to detect Vulkan SDK
    
    In order to build dnn with Vulkan support, need installing
    Vulkan SDK and setting environment variable "VULKAN_SDK" and
    add "-DWITH_VULKAN=ON" to cmake command.
    
    You can download Vulkan SDK from:
    https://vulkan.lunarg.com/sdk/home#linux
    
    For how to install, see
    https://vulkan.lunarg.com/doc/sdk/latest/linux/getting_started.html
    https://vulkan.lunarg.com/doc/sdk/latest/windows/getting_started.html
    https://vulkan.lunarg.com/doc/sdk/latest/mac/getting_started.html
    respectively for linux, windows and mac.
    
    To run the vulkan backend, also need installing mesa driver.
    On Ubuntu, use this command 'sudo apt-get install mesa-vulkan-drivers'
    
    To test, use command '$BUILD_DIR/bin/opencv_test_dnn --gtest_filter=*VkCom*'

    * dnn/Vulkan: dynamically load Vulkan runtime
    
    No compile-time dependency on Vulkan library.
    If Vulkan runtime is unavailable, fallback to CPU path.
    
    Use environment "OPENCL_VULKAN_RUNTIME" to specify path to your
    own vulkan runtime library.

    * dnn/Vulkan: Add a python script to compile GLSL shaders to SPIR-V shaders
    
    The SPIR-V shaders are in format of text-based 32-bit hexadecimal
    numbers, and inserted into .cpp files as unsigned int32 array.
    
    * dnn/Vulkan: Put Vulkan headers into 3rdparty directory and some other fixes
    
    Vulkan header files are copied from
    https://github.com/KhronosGroup/Vulkan-Docs/tree/master/include/vulkan
    to 3rdparty/include
    
    Fix the Copyright declaration issue.
    
    Refine OpenCVDetectVulkan.cmake
    
    * dnn/Vulkan: Add vulkan backend tests into existing ones.
    
    Also fixed some test failures.
    
    - Don't use bool variable as uniform for shader
    - Fix dispathed group number beyond max issue
    - Bypass "group > 1" convolution. This should be support in future.
    
    * dnn/Vulkan: Fix multiple initialization in one thread.
