Remove omp_get_max_threads (#7608)

Browse Source 
This is the one last PR for removing omp global variable.

* Add context object to the `DMatrix`.  This bridges `DMatrix` with https://github.com/dmlc/xgboost/issues/7308 .
* Require context to be available at the construction time of booster.
* Add `n_threads` support for R csc DMatrix constructor.
* Remove `omp_get_max_threads` in R glue code.
* Remove threading utilities that rely on omp global variable.
