shiboken: Add allow-thread attribute to type system and class entries

In the typesystem parser, add the allow-thread attribute to root and
complex type entry.

Rewrite the handling of allow-thread (cached) in AbstractMetaFunction
similar to the exception handling (store the modification in
AbstractMetaFunction and go down the class hierarchy if it is
unspecified).
