Ray Tracing Pipeline and Demo, moved out fresnel functions from math.hlsl to bxdf, more complete tgmath

The ICPU asset-version of the pipeline not done yet, the creation parameters of the RT pipeline are subject to change ( #839 ).

Added utilities:

• system::isDebuggerAttached
• erf and erfInv functions in tgmath
• TEA, LCG, and PCG in nbl::hlsl::random

Bugfixes:

• circular deps in concepts
• fix make_unsiged trait

vk::BufferPointer equivalent, tgmath.hlsl , Complete C++/HLSL/GLSL intrinsic parity, float64_t emulation with uint64_t, Multiple Entry Point HLSL Shader Compilation, Updated Vulkan Baseline, Resizable LRU Cache

DXC has been forked

Important: Nabla uses a custom fork of DirectX Shader Compiler, where you can annotate an inout variable with [[vk::ext_reference]] to prevent copy-in-copu-out calling convention and retain pass-by-restrict-reference.

v0.5.1-alpha : C++20-like Concepts in HLSL202x

C++20-like concepts added to our HLSL Header library, try it at http://godbolt.nsc.devsh.eu

Examples 01,02,03,04,05,06,07,08,09,10,11,12,20,21,22 - cppcompat,23,24,61,62 are tested and known to work.

New Asset Converter

Completely de-duplicates all resources based on contents (their hashes) and merkle-tree equivalents for DAGs.

Doesn't handle BLAS and TLAS construction yet and mip-map recalculation/generation.

Examples 01,02,03,04,05,06,07,08,09,10,11,12,20,21,22 - cppcompat,23,24,61,62 are tested and known to work.

Fix a few Examples

Examples 01,02,05,06,07,09,10,29,33,34,35,38,55,61-UI,both 62 are tested and known to work.
