Add increased inline threshold (iff Clang) to exported Ceres target.

- When compiled with Clang, Ceres and all of the examples are compiled
  with an increased inlining-threshold, as the default value can result
  in poor Eigen performance.
- Previously, client code using Ceres would typically not use an
  increased inlining-threshold (unless the user has specifically added
  it themselves).  However, increasing the inlining threshold can result
  in significant performance improvements in auto-diffed CostFunctions.
- This patch adds the inlining-threshold flags to the interface flags
  for the Ceres CMake target s/t any client code using Ceres (via
  CMake), and compiled with Clang, will now be compiled with the same
  increased inlining threshold as used by Ceres itself.
