spellcheck: windows and macos

Implement the hunspell spellchecker for Windows and MacOS. It also
changes the base implementation for Linux. The system dictionaries
(if any) are aggregated with those installed from the LibreOffice
repository via Jami's dictionary management interface.

This commit implements a major refactoring of the spellcheck system
to improve UI responsiveness and user experience:

Core Changes:
- Used QAbstractListModel to represent the list of dictionaries
- Added new QML components:
  - DictionaryInstallView.qml
  - ManageDictionariesDialog.qml
  - SpellCheckLanguageComboBox.qml
- Updated property names for clarity
- Fixed a bug in the settings combo box custom component that caused
  out-of-range errors for filtered models
