This patch is to render the YUV(NV formats family) frame by OpenGL shader.
I rework viewfinder class and give viewfinder handle abstract class as interface 
and make it able to handle viewfinder and viewfinderGL both.

I tested on rockpi4b with kernel 5.7rc4+imx219 camera module.

Hi Laurent,

Sorry I forgot to have a brief description about what's the difference with
the v1.
Mainly,
1. To have a viewfinder handle interface to handle viewfinder and
viewfinderGL both.
2. able to select different NV formats family by the YUV format.
3. and some changes according to the v1's review comments.

BR,
Show
