rtos: facilitate RTOS SMP handling
The RTOS handlers present OS threads to gdb but the openocd
target layer only knows about CPU cores (hardware threads).
This patch allows closing this gap inside the RTOS handler.
The default implementation just returns the current core, but
a RTOS handler can provide its own function that associates a
an OS thread with a core.
