fix: windows crashes & builds (#55)

- Doing jobs in parallels in GHA (Divide build time by 3).
- Now use custom webrtc builds for this repo
- Windows crashes when receiving video is now fixed (thanks @cloudwebrtc)
    - Now reading defines from webrtc.ninja
- Added a small create_pc test to be sure libwebrtc is working/linked correctly 
- Fix MacOS builds 
- Fixed Linux duplicated main build error (due to nasm)
