qdoc: Unify generated documentation between \typedef and \typealias

\typedef can be used as a substitute for \typealias for documenting
aliases. Since they are identical in terms of usage, unify also the
way they are documented:

- Remove 'typedef' and '(alias)' from both the summary and details
  sections, making both appear as types.

- Remove automatically generated 'This is a type alias for ...' note
  for type aliases. This typically resulted in duplicate statements.

- Use '-typedef' anchor suffix for both.

- Use 'typedef' as element for both in .index files and webxml output
  format.

- Add template parameters for type aliases for DocBook generator;
  these were previously missing.
