Fixed gcc 11.1 compilation errors

[Light7734]

Arch Linux x86_64 - gcc 11.0.0 x86_64-pc-linux-gnu

ShaderConductor.hpp uses uint*_t types but hasn't included stdint.h ShaderConductor.cpp has std::atomic<ULONG> m_ref = 0; which gives: error: use of deleted function 'std::atomic<long unsigned int>::atomic(const std::atomic<long unsigned int>&)'

Use of deleted function with std::atomic
