Merge branch 'main' into nac-spice22x

Merge official spice2x 'main', up to b53447b
Notes: dc82c98  is where the nixac fork starts.

- Upstream's OBJECT-library + forbidden-static-DLL-import build refactor
  merged with nixAC's blob/dsdmo resources
- SPICE_XP / runtime large-address-aware detection builds have been
  integrated from upstream
- README.md grabs from upstream; .gitignore keeps nixAC's fork-specific
  entries
