mbed_rtx_idle: uVisor: Don't attempt to sleep

When uVisor is enabled, don't attempt to sleep. Attempting to sleep will
fail, as per <https://github.com/ARMmbed/uvisor/issues/420>.

Add tickless support for devices without SysTick

Some Cortex-M0 devices, such as the nrf51, don't have the SysTick.
Instead, these targets use a software interrupt to simulate SysTick.
Add the hooks in the tickless code to support these devices. Targets
which do not have SysTick should now define NO_SYSTICK in targets.json
and implement mbed_get_m0_tick_irqn to add os suport.

This patch also removes os tick handling from the existing devices
(nrf51) since this is now handled in common code.

Add initial support for tickless RTX

Add support for tickless by replacing RTX's SysTick timer code with
with code which uses an mbed timer along with suspending and
resuming the kernel in the idle loop. Tickless is enabled on a
per-target basis by defining the macro MBED_TICKLESS.
