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.

1The tests were designed to operate in a very controlled environment.  If
2one uses interrupt-driven console output, then tasks will block unexpectedly
3when a buffer filles and interrupts will perturb with the task execution order.
4
5The tmtests should only be run with all interrupt sources disabled using
6polled IO.

8The following is a list of reported failures from running the tests on
9a board with interrupt driven console IO.  These problems do not
10occur when using polled IO.
