Remove experimental flags for symmetric GF struct

Following flags are removed here:
- MULTI_LVL_BOOST_VBR_CQ
- NEW_MULTI_LVL_BOOST_VBR_ALLOC
- REDUCE_LAST_GF_LENGTH
- REDUCE_LAST_ALT_BOOST

These were on by default already, and multiple experiments have shown
that they provide gains.
So, no need for a knob to turn them off.
