Add bit-level propagation support to BV bitblast solver. (#5906)
This commit adds support for bit-level propagation for the BV bitblast solver to quickly detect conflicts on effort levels != FULL. Bit-level propagation for the bitblast solver is by default disabled for now. Further, bit-blasting of facts is now handled more lazily with a bit-blast queue.
