Introduce `atomic` type for iceoryx #200

Closed elfenpiff closed 1 month ago

elfenpiff commented 2 months ago

Brief feature description

Our Atomic* strategy has currently the problems that:

on 32-bit AtomicU64 is not available, not even with a mutex like in the C++ STL
cannot be tested with loom
that all atomic do not support other types with the same alignment/size that are not provided by the default types
they cannot be overloaded for advanced error handling strategies like fail in a compare-exchange loop

The new atomic shall be exchangeable via feature flags.

ToDo

[x] Implement atomic
[ ] add feature flag
[x] Integrate atomic in iceoryx so that everything uses the atomic
