Sona Kurazyan 376715f1a5 Remove usages of deprecated APIs of qtbase/widgets
- Replace the usages of deprecated APIs by corresponding
  alternatives in the library code and documentation.

- Build docs for deprecated APIs conditionally, based on deprecation
  version. Remove the docs of methods deprecated since 5.0.0, these
  methods are not compiled anymore.

- Modify the tests to make them build when deprecated APIs disabled:
    * Make the the parts of the tests testing the deprecated APIs to
      be compiled conditionally, only when the corresponding methods
      are enabled.
    * If the test-case tests only the deprecated API, but not the
      corresponding replacement, add tests for the replacement
