[CSM] Add minimap API modifiers (#5399)

* Rename Mapper (too generic) to Minimap
* Add lua functions to get/set position, angle, mode for minimap
* Client: rename m_mapper to m_minimap
* Add minimap to core.ui namespace (core.ui.minimap)
* Add various functions to manage minimap (show, hide, toggle_shape)
* Cleanup trivial declaration in client

+* `get_pos()`: returns the minimap current position
+* `set_angle(deg)`: sets the minimap angle in degrees
+* `get_angle()`: returns the current minimap angle in degrees
+* `set_mode(mode)`: sets the minimap mode (0 to 6)
+* `get_mode()`: returns the current minimap mode
+* `toggle_shape()`: toggles minimap shape to round or square.
