ipc: Allow all trivially copyable objects to be passed directly into WriteBuffer (#4465)
* ipc: Allow all trivially copyable objects to be passed directly into WriteBuffer
With the support of C++20, we can use concepts to deduce if a type is an STL container or not.
* More agressive concept for stl containers
* Add -fconcepts
* Move to common namespace
* Add Common::IsBaseOf
