Do real chroma RDO search for CDEF

Chroma now has a list of strenghts too, with the superblock signalling
shared between luma and chroma.

low-latency, cpu=4:

   PSNR | PSNR Cb | PSNR Cr | PSNR HVS |   SSIM | MS SSIM | CIEDE 2000
-0.0114 | -1.4626 | -1.4745 |  -0.0423 | 0.0430 | -0.0001 |    -0.7416
