Test arbitrary large descriptor binding numbers

Test arbitrary large descriptor binding numbers

Added tests where descriptor sets use very large binding numbers
with huge gaps between numbers. The largest binding number used
is 0xFFFEu as it is the largest value accepted by Glslang.

Large binding numbers are tested with various shader stages and
buffer types.

New tests:

dEQP-VK.binding_model.shader_access.*.multiple_arbitrary_descriptors.*

Components: Vulkan

VK-GL-CTS issue: 390
