Merge "Vulkan compute 0 only requires variable pointers" into oc-dev

     * will enumerate at least one {@code VkPhysicalDevice}, and the feature version will indicate

     * what level of optional compute features are supported beyond the Vulkan 1.0 requirements.

     * <p>

     * Compute level 0 indicates support for:

     * <ul>

     * <li>Ability to use pointers to buffer data from shaders</li>

     * <li>Ability to load/store 16-bit values from buffers</li>

     * <li>Ability to control shader floating point rounding mode</li>

     * </ul>

     * Compute level 0 indicates support for the {@code VariablePointers} SPIR-V capability defined

     * by the SPV_KHR_variable_pointers extension.
