Enforcing --no-bv-eq, --no-bv-algebraic and --no-bv-ineq when proofs are enabled (#1801)

Currently, if the user enables proofs but does not disable the algebraic/equality/inequality bv-solvers, then we reach an internal error while printing the proof (unreachable code becomes reachable).
This commit auto-disable these bv options when proofs are enabled, unless these options were set by the user. In such a case, an error message is given to the user.
