A passing test on the CI's cppyy test job contains a memory leak on with LLVM 16 that is unexpected and should be fixed

We seem to be calling an invalid delete[] operator when the Interpreter invokes the JitCall, during CPyCppyy's method execution pipeline (CPyCppyy::CPPMethod::Execute)

The test responsible is test_lowlevel/test06_ctypes_as_ref_and_ptr, something like:

# integer types
  i = POINTER(ctypes.c_short)();        ctd.set_short_ppa(i)
  assert i[0] ==  -1; assert i[1] ==  -2; assert i[2] ==  -3
  cppyy.ll.array_delete(i)

Valgrind report:
