validation: Code for timer cancel & rests tests

This additional manual crafted code is needed to compile
the timer manager tests for rtems_timer_cancel() and
rtems_timer_reset().

validation-2.yml:
  Add the new test files.

testsuites/validation/tx-timer-server.c:
  New functions to permit tests to read RTEMS timer internal states.
