Add explicit no sparse linear algebra library available option.

- Previously we had no defined default value for
  sparse_linear_algebra_library_type in Solver::Options if Ceres
  was compiled with no sparse library available.  Thus in that case,
  the default value (dependent upon the compiler) would indicate that
  one was available.
- Now we have an explicit option that means no sparse library is
  available, which is now the default value in Solver::Options in this
  case.
- Add a warning in CMake when the user disables all sparse libraries.
- Fix typos in trust_region_preprocessor_test:
  (SUITE/CX)_SPARSE -> (SUITE/CX)SPARSE that induced failures when
  no sparse libraries were available.
