7205f3e35b cpp: Add spec of new operator with alignment request
C++17 delivered another specialization of a new operator,
that allows to allocate a memory with requested alignment.

The commit adds these specialziations to C++ subsystem.

a0dc682bd9 cpp: new: Add no-throwing implementation of new operator
C++ subsystem defines exception throwing operator new.
Though the implementation never throws an exception.

If used by an application it should verify if requested
memory was allocated. This is against C++ standard.
If an application does not support exceptions or does not
want to call throwing new operator, it should use a
specialization of a new operator that makes sure it
never throws bad_alloc exception. The cpp subsystem
does not provide this specialization.

The commit adds missing operator new specializations.

6ade720851 treewide: avoid use of unsupported C++ specifiers
constexpr and noexcept were introduced as specifiers in C++11.  Avoid
referencing them when compiling for earlier versions of the language.

8a98a67bf1 cpp: Use malloc/free instead of kernel variants in new/delete
Use malloc/free instead of k_malloc/k_free in operator new/delete
implementation or use libstdc++ implementation when available.

Further updated cpp_synchronization sample to enable minimal libc heap
as virtual destructor requires operator delete which depends on free.
