QDoc: Remove unused method and member from FunctionNode

The FunctionNode class contains the private member `m_parentPath` and
the associated public setter method setParentPath(). There is no
associated getter method, nor is the member variable ever read.
Furthermore, the setter is never called from anywhere.

Remove the member and setter as dead code. This reduces the public
API of the FunctionNode class and unclutters its internals just a bit.
