freertos(IDF): Restore vanilla task selection algorithm for single core
This commit restores the vanilla behavior for taskSELECT_HIGHEST_PRIORITY_TASK
when configNUM_CORES == 1 && configUSE_PORT_OPTIMISED_TASK_SELECTION == 0. This
results in the SMP selection algorithm (taskSelectHighestPriorityTaskSMP) to
only be run when configNUM_CORES > 1.
