Debugger: Show text representation for 'char *' typedefs etc

'tryPutSimpleFormattedPointer' takes care of nicely
showing the actual string representation of character
arrays if the innerType is one of 'char', 'signed char',
unsigned char', 'CHAR'.

To make this work for typedefs of those types as well,
first resolve the typedef before passing the value to
'tryPutSimpleFormattedPointer' from 'putFormattedPointerX'.

This e.g. improves the display of variables of type
'const gchar *'.
