Update LAPACK option to refer to direct use by Ceres only.

- Previously the LAPACK option meant would Ceres link against LAPACK,
  whether directly or indirectly via SuiteSparse (if SUITESPARSE=ON),
  as such if LAPACK=OFF, the use of SuiteSparse was disabled, even if
  it was found.
- To support the use-case of using a limited LAPACK implementation that
  satisfies SuiteSparse’s requirements, but potentially not Ceres’ we
  now adopt the more conventional terminology whereby the LAPACK option
  refers only to whether Ceres itself will directly call LAPACK
  routines, not whether it or any of its dependencies will.
- This means that the LAPACK and SUITESPARSE options are now
  independent.
- Also unnecessary calls to find_package(BLAS), as find_package(LAPACK)
  already searches for BLAS, and appends the resulting libraries to
  LAPACK_LIBRARIES if they are found.
