LOG: [lldb-dap] Do not show memory address on types with no summary (#172670)

Majority of the time users are less interested on the memory address of
a type. It is mostly useful for pointer types (the memory address is
shown).
It makes the view more bloated without adding useful information.

can always fall back to the debug console or watch pane to view the
information if necessary.

Added: 
    

Modified:

    lldb/test/API/tools/lldb-dap/variables/TestDAP_variables.py
    lldb/tools/lldb-dap/JSONUtils.cpp

Removed:
