Make option names related to CEGQI consistent (#4316)

This updates option names to be consistent across uses of counterexample-guided quantifier instantiation (ceqgi), which was previously called "counterexample-based quantifier instantiation" (cbqi), and sygus.

Notably, the trace "cegqi-engine" is changed to "sygus-engine" by this commit.

The changes were done by these commands in the given directories:

src/:
for f in $(find -name '.'); do sed -i 's/options::cbqi/options::cegqi/g' $f;sed -i 's/cegqi-engine/sygus-engine/g' $f; done;sed -i 's/"cbqi/"cegqi/g' $f; done
test/regress/:
for f in $(find -name '.'); do sed -i 's/--cbqi/--cegqi/g' $f; done
src/: and test/regress/:
for f in $(find -name '.'); do sed -i 's/cegqi-si/sygus-si/g' $f; done
test/regress/:
for f in $(find -name '.'); do sed -i 's/no-cbqi/no-cegqi/g' $f; done
test/regress/:
for f in $(find -name '.'); do sed -i 's/:cbqi/:cegqi/g' $f; done

And a few minor fixes afterwards.

This should be merged close to the time of the next stable release.
