Remove a whole bunch of unused annotations from gVCF output.

AC,AF,AN,FS,QD - they'll all be recomputed later.
BLOCK_SIZE and MIN_GQ were not necessary.

I also made the StrandBiasBySample annotation forced on when in gVCF mode.
It turns out that its output wasn't compatible with BCF so I patched it (and the variant jar too).
