Add data type code generator

This change adds a code generator which generates data classes,
enums and encoder/decoder methods for OPC UA data type descriptions
in a .bsd file.

The generated data classes provide a getter and setter based API
that follows the structure of the types available in Qt OPC UA.
If a structure field's type is already available in Qt OPC UA,
it will be used in the data class instead of generating a new
data class for it.

The decoder/encoder operates on QOpcUaExtensionObject as well as
QByteArray and can be used to turn received binary encoded values
into easily accessible structured data as well as to create
binary encoded extension objects for writing custom types or for
parameters in method calls.
