QDoc: Code cleanup

* Use multiple arguments for QStrings instead of calling
  .arg() multiple times.
* Define trivial constructor/destructor '= default' instead of adding
  empty implementations.
* Remove unreachable code.
* Prefer ranged-based for loops.
* Initialize with auto from static_cast<>() and new.
* Simplify expressions.
* Prefer "QList::empty()" over "QList::size() > 0".
* Remove unused method.
* Return qsizetype instead of int to avoid narrowing conversion.
* Remove unused include.
* Remove unreachable return statement.
* Prefer raw string literals over escaped regexes.
* Initialize struct members.
* Make variables used as const refs const refs.
* Use std::move instead of passing const ref in ctor.
* Drop redundant 'virtual' from methods marked 'override'.
* Make local copies that arent ever modified const refs to avoid copying.
* Turn for-loop into std::any_of.
* Made single-argument constructor explicit.
* Don't shadow variable names from outer scope if not necessary.
* Remove const at top level that does not improve const correctness.
* Update copyright notice for affected classes.
