Revert AutoSpecialize as default for all SciMLFunction constructors

The change in #1298 exposed multiple breaking issues:
- BigFloat tableau coefficients promote t past FunctionWrapper signatures
- GradientTracer/sparsity detection types not in wrapper signatures
- MatrixOperator jac_prototype causes promote_op → Union{} in promote_f
- Hard DAE numerical accuracy regression with wrapped functions

Deferring this to v4 where the underlying issues (tableau two-type
constructors, promote_f robustness) can be addressed properly.
