[dist-8x8] Enforce partition and tx size 8x8 or larger

Because of the incompleteness, unreliability and difficult maintainability of the
code, which are deeply coupled with RDO-based mode decision, CONFIG_DIST_8X8 experiment
enforces RDO mode decision to use 8x8 or larger partition and
transform block sizes.

If --tune=[daala-dist|cdef-dist] is given, min partition size is enforced
to 8x8 pixels (4x16 and 16x4 are excluded as well) and tx_size < 8x8 is
excluded during RDO search.

To see the performance change of "--tune=[daala-dist|cdef-dist]",
compare with --enable-dist-8x8, which have the same mode decision options but
RDO uses PSNR as a distortion metric.
