sys/bit: provide CPU_HAS_SRAM_BITBAND

CPU_HAS_SRAM_BITBAND can be used to check whether bit-banding is supported for
all of SRAM. With partially supported bit-banding, this feature is more of a
foot gun that a valuable tool.

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.
