Use enum class in the public API

This change was suggested in the API review.

All the "old" enums are backwards compatible in QML, since unscoped
values are enabled by default.

Added the following new enum values maintaining compatibility (in QML):
- QVirtualKeyboardInputEngine::PatternRecognitionMode::None (same as PatternRecognitionDisabled)
- QVirtualKeyboardInputEngine::PatternRecognitionMode::Handwriting (same as HandwritingRecoginition)
- QVirtualKeyboardSelectionListModel::Role::Display (same as DisplayRole)
- QVirtualKeyboardSelectionListModel::Role::WordCompletionLength (same as WordCompletionLengthRole)

Renamed the following enum values (new in 5.12):
- QVirtualKeyboardSelectionListModel::Role::Dictionary (was DictionaryTypeRole)
- QVirtualKeyboardSelectionListModel::Role::CanRemoveSuggestion (was CanRemoveSuggestionRole)
- QVirtualKeyboardSelectionListModel::DictionaryType::Default (was DefaultDictionary)
- QVirtualKeyboardSelectionListModel::DictionaryType::User (was UserDictionary)

Added missing Q_DECLARE_METATYPE for:
- QVirtualKeyboardInputEngine::PatternRecognitionMode
- QVirtualKeyboardInputEngine::ReselectFlag
- QVirtualKeyboardSelectionListModel::DictionaryType

The enums can be found in:
- src/virtualkeyboard/qvirtualkeyboardinputengine.h
- src/virtualkeyboard/qvirtualkeyboardselectionlistmodel.h

Added a test case for verifying QML enum values.
