port: CMapOutdoor + PythonBackground + minimap (1:1 40250)

GameLib map/area/terrain units, PRTerrainLib Terrain/TextureSet,
PythonBackground(+Module) and ColorTransitionHelper ported verbatim;
pending stand-ins and background module stubs removed. Hand edits:
BeginEnvironment's pointer tag via uintptr_t, LoadWaterMap reads the
file's 32-bit longs. Terrain draw passes stay platform no-ops (Godot
draws the terrain). RecordingDevice gains textures, buffers and render
targets; orthographic draws become UI commands so CPythonMiniMap's
masked tiles show through minimap_image_filter in python_ui_surface.
