Throw better error for unsupported constraint types

[odow]

See https://discourse.julialang.org/t/issues-solving-a-bilevel-optimization-with-binary-variables/105460

The unhelpful error is

Constraints of function MathOptInterface.SingleVariable in the Set MathOptInterface.ZeroOne are not implemented
