INFOPLAT-3111: Fix atomic swapper for otel zap core

[kirqz23]

The AtomicCore.With() method was breaking the atomic chain when fields were applied to the logger, preventing swapping of otel core correctly. The main issue was that d.load().With(fs) was returning totally new noop core disconnected from atomic core.

func (d *AtomicCore) With(fs []zapcore.Field) zapcore.Core {
    return d.load().With(fs) 
}

The fix introduces a weak pointer solution that maintains atomic core connections while preventing memory leaks and tracks child cores created via .With() calls.
