[Breaking] Add global versioning. (#4936)
* Use CMake config file for representing version.

* Generate c and Python version file with CMake.

The generated file is written into source tree.  But unless XGBoost upgrades
its version, there will be no actual modification.  This retains compatibility
with Makefiles for R.

* Add XGBoost version the DMatrix binaries.
* Simplify prefetch detection in CMakeLists.txt
