remove GenericSVD and GenericSchur as dependencies

Due to type piracy, these packages cause problems with precompilation and don't play nice with GenericLinearAlgebra (see discussion in JuliaLinearAlgebra/GenericLinearAlgebra.jl#71). Additionally, GenericSVD has now been deprecated (JuliaLinearAlgebra/GenericSVD.jl#30).
