media: amphion: Trigger source change if colorspace changed

Browse source

After encountering a colorspace change in the stream, the decoder
sends a V4L2_EVENT_SOURCE_CHANGE event with changes set to
V4L2_EVENT_SRC_CH_RESOLUTION.

Then the client can detect and handle the colorspace change without any
buffer reallocation
