drivers/video: add GC0308 VGA CMOS image sensor driver

Add support for the GalaxyCore GC0308 VGA CMOS image sensor.
The driver implements the NuttX imgsensor interface and supports
VGA (640x480), QVGA (320x240), and QQVGA (160x120) resolutions
via Kconfig selection. Output format is RGB565X (big-endian).
