pw_boot_cortex_m: Rename pw_boot_armv7m to pw_boot_cortex_m:armv7m

Since the implementation is closer to a generic Cortex-M implementation,
rename pw_boot_armv7m to pw_boot_cortex_m, and add a core-specific
target named "armv7m".

This matches pw_cpu_exception_cortex_m.

Toolchain definitions will need ot be changed from:
  pw_boot_BACKEND = dir_pw_boot_armv7m
to
  pw_boot_BACKEND = "$dir_pw_boot_cortex_m:arm7vm"
