Fix outdated comments and add missing ESP32-C5 support in CLI

- Update chip.go comments to include ESP32-S2 in magic value detection
- Add ESP32-C5 to USB-JTAG/Serial reset comment in reset.go
- Add missing esp32c5 to -chip flag and parseChipType() in main.go
- Add missing auto to -reset flag and reset mode switch in main.go
