Restructure esp32c6 to extend esp32_idf_V5

- esp32c6 section now properly extends esp32_idf_V5 like other variants (S2, C3)
- Removed duplicate lib_deps, now inherits from esp32_idf_V5
- Fixed comment typo (ESP32-C3 -> ESP32-C6)
- Use full GifDecoder hash for git fetch compatibility

Tested: esp32c6dev_4MB and esp32_wrover both build successfully.
