This will facilitate bringing the zero node into the token set while
allowing its probability to vary independently.

Preliminary tests indicated that these changes make cost_coeffs
approximately 20% faster which is a 2% improvement overall

Various additional changes were made to make the experiment
compatible with misc_fixes.
derflr: +0.979%
hevcmr: +0.865%
Speed-wise with --enable-supertx the encoder is only about 10%
slower than without. Decoding impact is about 30% slowdown.
Note this does not work with ext-tx or var-tx yet. That is
a TODO.

Add palette mode for keyframe luma channel. Palette mode is enabled
when using "--tune-content=screen" in encoding config parameters.
on screen_content testset: +6.89%
on derlr : +0.00%
