[groups] Remove NDEBUG from GroupSession.h (#16445)
Browse files Browse the repository at this point in the history
* [groups] Remove NDEBUG from GroupSession.h

Using NDEBUG to change public structure layouts is
problematic since it may introduce hard to debug bugs when
integrating the CHIP library with external components that
are built with different compiler options.

* Restyled by whitespace

* Remove ReferenceCounted completely as suggested by the author
