Revert of "Mark bogus palette color probabilities as zero".

Reverted commit: f8306bfdc (with some changes).

Reason: This was triggering an assert in debug build because of zero
probability values. So, using an "UNUSED_PROB" macro to replace these to
retain clarity.

Assertion failure can be reproduced as follows:

$ make clean; extra_cflags='-O0 -g -fno-inline' ../../configure
--enable-debug --enable-experimental --enable-palette && make -j 16

$ ./aomenc -D --codec=av1 ~/videos/screen_content_set/gimp.y4m -o
/tmp/foo.webm --tune-content=screen --limit=50

Pass 1/2 frame   50/51      8976B    1436b/f   86169b/s 2902620 us
(17.23 fps)
Pass 2/2 frame   25/0          0B 2933053 us 8.52 fps [ETA  unknown]
aomenc: ../../av1/encoder/cost.c:46: cost: Assertion `prob != 0' failed.
