qapi: provide a friendly string representation of QAPI classes 

If printing a QAPI schema object for debugging we get the classname and
a hex value for the instance:

  <qapi.schema.QAPISchemaEnumType object at 0x7f0ab4c2dad0>
  <qapi.schema.QAPISchemaObjectType object at 0x7f0ab4c2dd90>
  <qapi.schema.QAPISchemaArrayType object at 0x7f0ab4c2df90>

With this change we instead get the classname and the human friendly
name of the QAPI type instance:

  <QAPISchemaEnumType:CpuS390State at 0x7f0ab4c2dad0>
  <QAPISchemaObjectType:CpuInfoS390 at 0x7f0ab4c2dd90>
  <QAPISchemaArrayType:CpuInfoFastList at 0x7f0ab4c2df90>
