Do not enforce a specific C++ standard

Current language standard selection mechanism is quite convoluted and
the logic for propagating a specific C++ language standard (which cannot
be fully enforced anyway) is unnecessarily complicated. Instead
communicate the minimum required C++ standard and let CMake handle the
requirement. This allows the compiler and consumers to use newer
language revisions if available. The language standard used to compile
Ceres solver can still be set via `CMAKE_CXX_STANDARD`.

Move to CMake 3.10 which is supported by Ubuntu 18.04 LTS and simplify
the corresponding language features request.
