[MLIR][Vector] Remove implicit bitcast behavior from vector.extract (#186383)

Drop the `isCompatibleReturnTypes` override on `ExtractOp` that allowed
`vector.extract` to return a `vector<1xT>` when the natural inferred
return type is scalar `T` (and vice versa). Switch the op from
`InferTypeOpAdaptorWithIsCompatible` to `InferTypeOpAdaptor` to match.
