config: Add _Thread_Idle_stack_size

Move the idle thread stack size configuration constant out of the
configuration table.

Add THREAD_IDLE_STACK_SIZE_DEFAULT and use it to provide a default
definition of the idle thread stack size constant.

Update #3875.

89	* a variety of reasons:
90	*
91	* Reasons estimate is too high:

94	* Reasons estimate is too low:

96	* + messages

616	* @brief Maximum priority configuration.
617	*
618	* This configures the maximum priority value that
619	* a task may have.
620	*
621	* The following applies to the data space requirements
622	* of the Priority Scheduler.
623	*
624	* By reducing the number of priorities in a system,
625	* the amount of RAM required by RTEMS can be significantly
626	* reduced. RTEMS allocates a Chain_Control structure per
627	* priority and this structure contains 3 pointers. So
628	* the default is (256 * 12) = 3K on 32-bit architectures.
629	*
630	* This must be one less than a power of 2 between
631	* 4 and 256. Valid values along with the application
632	* priority levels and memory saved when pointers are
633	* 32-bits in size are:
634	*
635	* + 3, 2 application priorities, 3024 bytes saved
636	* + 7, 5 application priorities, 2976 bytes saved
637	* + 15, 13 application priorities, 2880 bytes saved
638	* + 31, 29 application priorities, 2688 bytes saved
639	* + 63, 61 application priorities, 2304 bytes saved
640	* + 127, 125 application priorities, 1536 bytes saved
641	* + 255, 253 application priorities, 0 bytes saved
642	*
643	* It is specified in terms of Classic API priority values.
