imx-boot: generalize Cortex-M default image handling 

Different platforms use different Cortex-M processors, so instead of
using the M4_DEFAULT_IMAGE_MX95 (as meta-imx does) for an M7 processor,
generalize to the CORTEXM_DEFAULT_IMAGE variable name. Also, move it
to the imx-boot recipe (where it is used) and deploy that image to
the imx-boot-tools directory, so the imx-boot image can be regenerated
externally (without yocto).
