closes #143466

CursorConfiguration

• Adds fontInfo as a dependency
• Uses fontInfo to determine the lineHeight instead of getting it explicitly (removes lineHeight dependency).
• Uses fontInfo to determine the typicalHalfwidthCharacterWidth

CoreNavigationCommands

• In each scrolling command, use EditorScrollImpl.runCoreEditorCommand instead of EditorScrollImpl._runEditorScroll and pass EditorScroll_.RawArguments
• Adds horizontal units and directions to EditorScroll_.Unit and EditorScroll_.Direction
• EditorScrollImpl.runCoreEditorCommand determines the scrolling method from the direction and the unit if they are compatible
• The horizontal scrolling unit used for the shortcuts is Column (typicalHalfwidthCharacterWidth).
• Each of scrollLeft and scrollRight scroll two columns (this more or less matches the pace of the vertical scroll)
• However, horizontal scrolling does not guarantee landing after exactly two columns because of the flooring done in scrollable; typicalHalfwidthCharacterWidth is usually a float while integer values are forced in the viewLayout's scrollable
• args.revealCursor is still not implemented
• No default keyboard shortcut is configured for horizontal scrolling
