Add tune entries for all Arm Cortex-M processors currently supported in
GCC (that are not currently present). The ARMv7 entries were added in
conf/machine/include/ to match the existing Cortex-M and Cortex-A tune
files. The ARMv8 entries were added to conf/machine/include/arm/armv8-m
to match how ARMv8 was done for Cortex-A processor tune files.
