[Enhancement]: introduce conditional noexcept

[kamilsa]

Description

After internal discussion in the team it was decided that we need to conditional noexcept instead of original noexcept function. Conditional noexcept could be defined in a form:

#ifdef ENABLE_NOEXCEPT // Assuming you have defined this flag during compilation
#define CONDITIONAL_NOEXCEPT noexcept
#else
#define CONDITIONAL_NOEXCEPT 
#endif

// Usage
void myFunction() CONDITIONAL_NOEXCEPT {
    // ... function implementation
}

Motivation

Motivation is to take advantage of using noexcept:

1. Compiler's optimization of noexcept functions
2. Clarity of developers intent when it is observed that function is defined as noexcept

At the same time noexcept can bring some additional challenges such as runtime termination: if exception is thrown inside noexcept function, stack trace of the crash might be incomplete.

Therefore it makes sense to put noexcept under conditional #define defined during compilation time

Additional context

It makes sense to introduce such define in qtils repo, to take advantage of such define in any project (KAGOME, libp2p, etc)

Are you planning to do it yourself in a pull request ?
