refactor: change methods ENTER|EXIT critical

The read and write of BaseType_t are atomic for a number of ports
and therefore, do not require taskENTER_CRITICAL/taskEXIT_CRITICAL.
This PR introduces portBASE_TYPE_ENTER_CRITICAL and
portBASE_TYPE_EXIT_CRITICAL which default to  taskENTER_CRITICAL
and taskEXIT_CRITICAL. The APIs that read/write BaseType_t are updated
to use these new macros. 

The next change would to be to define portBASE_TYPE_ENTER_CRITICAL and
portBASE_TYPE_EXIT_CRITICAL to nothing for ports where BaseType_t 
read and write are atomic.
