api: Remove deprecated Notepads

Notepads where a feature of RTEMS' tasks that simply functioned in
the same way as POSIX keys or threaded local storage (TLS). They were
introduced well before per task variables, which are also deprecated,
and were barely used in favor of their POSIX alternatives.

In addition to their scarce usage, Notepads took up unnecessary memory.
For each task:

  • 16 32-bit integers were allocated.
  • A total of 64 bytes per task per thread.

This is especially critical in low memory and safety-critical applications.

They are also defined as uint32_t, and therefore are not guaranteed to
hold a pointer.

Lastly, they are not portable solutions for SMP and uniprocessor systems,
like POSIX keys and TLS.

updates #2493.

57 *
58 * This module contains all RTEMS Configuration parameters.
59 *
60 * The model is to estimate the memory required for each configured item
61 * and sum those estimates.  The estimate can be too high or too low for
62 * a variety of reasons:
63 *
64 * Reasons estimate is too high:
65 *   + FP contexts (not all tasks are FP)
66 *
67 * Reasons estimate is too low:
68 *   + stacks greater than minimum size
69 *   + messages
70 *   + application must account for device driver resources
71 *   + application must account for add-on library resource requirements
72 *
73 * NOTE:  Eventually this may be able to take into account some of
74 *        the above.  This procedure has evolved from just enough to
75 *        support the RTEMS Test Suites into something that can be
76 *        used remarkably reliably by most applications.

750 *
751 * The following applies to the data space requirements
752 * of the Priority Scheduler.
753 *
754 * By reducing the number of priorities in a system,
755 * the amount of RAM required by RTEMS can be significantly
756 * reduced.  RTEMS allocates a Chain_Control structure per
757 * priority and this structure contains 3 pointers.  So
758 * the default is (256 * 12) = 3K on 32-bit architectures.
759 *
760 * This must be one less than a power of 2 between
761 * 4 and 256.  Valid values along with the application
762 * priority levels and memory saved when pointers are
763 * 32-bits in size are:
764 *
765 *   + 3,  2 application priorities, 3024 bytes saved
766 *   + 7, 5 application priorities, 2976 bytes saved
767 *   + 15, 13 application priorities, 2880 bytes saved
768 *   + 31, 29 application priorities, 2688 bytes saved
769 *   + 63, 61 application priorities, 2304 bytes saved
770 *   + 127, 125 application priorities, 1536 bytes saved
771 *   + 255, 253 application priorities, 0 bytes saved
772 *
773 * It is specified in terms of Classic API priority values.
