[Feature] Expose a public ThrowHelper type

[john-h-k]

Describe the problem this feature would solve

Currently, the Guard API is suitable for parameter validation but nothing more, and consumers still likely need a ThrowHelper type for other sorts of exceptions

Describe the solution

Expose a public ThrowHelper type (the current one internal) that provides throwing methods for a wider variety of types. The basic layout of each method would be

[DoesNotReturn]
public void ThrowFooException(string? message = null, Exception inner? = null)
{
    throw new FooException(message, inner);
}

With different params for exceptions with special ctors
