feat(board): add ESP32-S3 SparkBot board configuration

[ymzhang0319]

Depends on espressif/esp-gmf#48. End-to-end camera functionality requires the DVP XCLK pre-init fix in that PR; without it, the OV3660 sensor on SparkBot cannot be detected via SCCB on upstream esp_board_manager 0.5.10. Once that PR lands and a new esp_board_manager version is published, I'll bump dependencies.lock here in a follow-up commit.

Summary

• Add esp_sparkbot board under application/edge_agent/boards/espressif/esp_sparkbot/.
• 1.3" ST7789 SPI LCD, I2S audio (internal ADC in, DAC out), BMI270 IMU, OV3660 DVP camera.
• Add to .gitlab/ci/build.yml matrix.

Test Plan

Validated locally with ESP-IDF v5.5.4 and the upstream fix applied:

• YAML parses; Board Manager lists esp_sparkbot; clean idf.py build (2.67 MB, 36% headroom).
• On hardware: ov3660: Detected Camera sensor PID=0x3660, /dev/video2 opens from Lua, camera.capture() writes ~30 KB JPEG.

Notes

• Targets current SparkBot units (OV3660). Older batches use OV2640 at SCCB 0x30, XCLK 16 MHz — documented in README.
• PWDN and RESET are tied on the sensor module (-1 in yaml).
• Motor / chassis control (DRV8833) not in scope; will submit as follow-up after camera lands.

Thanks for the PR!

Could you please revert the changes to .gitlab/ci/build.yml and rebase this PR onto the latest master branch?

Thanks!

We discussed this with the ESP Board Manager maintainers. They would like to reproduce the issue first and look for a cleaner/more elegant solution for the problem your Board Manager PR is trying to address.

BTW, ESP Board Manager now has its own dedicated repository:
https://github.com/espressif/esp-board-manager

Done — reverted the .gitlab/ci/build.yml change and rebased onto the latest master. PTAL, thanks!

The added development board support seems to be independent from the ESP Board Manager or esp_video issue.

Therefore, we will proceed with merging this PR first, and handle the Board Manager / esp_video issue separately.

Thank you for your contribution!
