rtos: add instructions and helper code to make FreeRTOS work again
Run-time tested with FreeRTOS V8.1.2 (current version).
For the time being I propose this way of dealing with RTOSes that do
not export necessary information on their own.
I also suggest implementing a similar scheme for ChibiOS, exporting
the necessary struct fields' offsets via an OpenOCD-specific helper.
