gdb: better gdbarch init values
Change the initial values of the gdbarch structure fields to be nullptr, false or 0, depending on their types (instead of just 0). Define an `init_value()` method in the Value and Function classes to provide the appropriate initial value for the component. Use it at a few places in gdbarch.py.
