qdoc: Improve searching of collection nodes

QDocDatabase provided a way to search for a collection node in
the primary tree only. This was insufficient for use cases where
we want to list groups, C++ classes or QML types in other modules
using the \generatelist or \annotatedlist commands.

This commit does the following changes:
    - Add a function to find a collection node across all
      trees, use it for generating output for the list commands
      and generating C++ class/QML/JS type requisite tables.
    - Modify the code for \generatelist command to accept
      'qmltypesbymodule' and 'jstypesbymodule' as parameters.
    - Modify constness of some functions to enable above
      changes.
