Explicit Resource Bindings in OpenGL

[Jorgemagic]

Hi @gongminmin,

In this pull request I added several things:

Added Explicit resource bindings in OpenGL translation

HLSL

Texture2D DiffuseTexture : register(t0);
SamplerState Sampler : register(s0);
Texture2D DiffuseTexture2 : register(t1);

Produced explicit layout bindings in GLSL

layout(binding = 0) uniform sampler2D SPIRV_Cross_CombinedDiffuseTextureSampler;
layout(binding = 1) uniform sampler2D SPIRV_Cross_CombinedDiffuseTexture2Sampler;

This ensures the resource bindings are the same that in original HLSL.

More flexible load dependencies (dxcompiler) on windows

Before:
m_dxcompilerDll = ::LoadLibraryA(dllName);
Issue: Only search dxcompiler library in executable path and system paths, now is possible load library from ShaderConductor library path.

Included libShaderConductorWrapper to cmake compilation

Now the AzurePipeline artifacts will include libdxcompiler, libShaderConductor, and libShaderConductorWrapper libraries.

(LPCSTR)"DllMain"
can be changed to
TEXT("DllMain")
to make it compatible to both MBCS and UNICODE. Or just use GetModuleHandleExA without C-style case to DllMain. Same as GetModuleFileName below.

Yes, I think that it is interesting.

Can be:
if(NOT SC_WITH_CSHARP)
return()
endif()
to avoid indent most lines in this file.
