5ad834ce28 videotestsrc: Support video/x-bayer 10/12/14/16 bit depths 
Add support for generation of 10/12/14/16 bit bayer test pattern.
The implementation is rather simplistic, just take the ARGB
input, generate 16-bit data out of it instead of 8-bit, shift
them as required by the output bitness, and apply endian swap.

Example usage:
```
$ gst-launch-1.0 videotestsrc ! \
    video/x-bayer,width=512,height=512,format=bggr12le ! \
    bayer2rgb ! \
    video/x-raw,format=RGBA64_LE ! \
    videoconvert ! \
    autovideosink
```

1b22ffdfbd videotestsrc: Don't re-render every frame when it's not needed. 
When the pattern being rendered by videotestsrc doesn't have motion,
cache a rendered buffer and output it repeatedly with updated
metadata.

Based on a patch by Edward Hervey <edward@centricular.com>
