Import Altium Projects

Handle Altium project file format

Parse individual schematic files and layout files
Create top-level schematic file
Link imported UUIDs between schematic symbol and footprints based on
refdes
Create KiCad project
Map Altium layout layers between KiCad

Fixes https://gitlab.com/kicad/code/kicad/-/issues/2117
