Add missing wxABI_VERSION checks and version script entries.

Newly overridden virtual methods must be taken in wxABI_VERSION checks as
otherwise any program using the class deriving from the one containing this
method would reference the method in the vtbl of that class and so become
ABI-incompatible with the earlier shared library versions.

Also add wxABI_VERSION guard around the entire wxSimplebookXmlHandler class
added in 3.0.2.
