feat(ci): dynamic solo firmware build workflow, add _solo_dual envs for Wio Tracker L1

- Add build-solo-firmwares.yml: auto-detects all _solo_dual envs from platformio.ini, builds in parallel, publishes uf2 files to draft release
- Remove build-wio-tracker-l1-firmwares.yml (replaced by solo workflow)
- Add WioTrackerL1_companion_solo_dual and WioTrackerL1Eink_companion_solo_dual envs
- Wire build-solo-firmwares command in build.sh using _solo_dual suffix
