#7667 - add API documentation

The scenario works as expected when disabling model compression:

```
from z3 import *
pre_processor = Tactic("bit-blast")
solver = Solver()

set_param("model.compact", False)

x = BitVec('x', 8)
pre_processed = pre_processor(x == 5)
print(pre_processed[0])
solver.add(pre_processed[0]) # add the sole assertion

if solver.check() == sat:
    print(solver.model())
    model = pre_processed[0].convert_model(solver.model())
    print(model)
    print(model[x].as_long())
```

The model may be null, in which case the returned model is valid if the goal was
established satisfiable.
When using this feature it is advisable to set the parameter \c model.compact to \c false.
It is by default true, which erases variables created by the solver from models.
Without access to model values for intermediary variables, values of other variables
may end up having the wrong values.
