cpu/cortexm_common: add XFA handling to linkerscript
...
The global core/ldscripts/xfa.ld doesn't match our cortexm_base.ld.
This commit directly adds the two XFA lines to cortexm_base.ld.
In addition to that, a dummy (empty) xfa.ld is added, which the linker will pick
instead of core/ldscripts/xfa.ld, effectingly not using it.

sys/bit: move bit.h from cortexm_common/ to sys/

The bit access functions are not tied to Cortex-M CPUs, here they only
provide optimisations via bit-banding.
But the functions are generally useful - so move them to an arch independent
location.

cpu/cortexm_common: flush pipeline before disabling interrupts in idle
...
When enabling & disabling interrupts back-to-back pending interrupts
are not serviced on Cortex-M23/M33.
Flush the pipeline to give interrupts a chance of executing in `sched_arch_idle()`.
This fixes `no_idle_thread` on Cortex-M23.

cortexm_common: Enable using pendsv IRQ at lower priority
...
This modifies the cortex-m thread specifics to allow running the PendSV
interrupt continuously at lower priority and removes the priority
modifications during the interrupt itself. Interrupts are disabled
during the scheduling itself, but enabled briefly after the sleep to
ensure that they are handled if activated during the scheduling or the
sleep.
