Relocate port source to zephyr/subsys/mcuboot_svc

Relocate `$mcuboot/boot/zephyr/*.c` files to
`$mcuboot/zephyr/subsys/mcuboot_svc/` to become a
reusable subsystem.

NOTE: keys.c was not put into `mcuboot_svc` as this
will need to be project-specific and may need to be kept
in a different module.

Verified by:
1. Building `$mcuboot/boot/zephyr` and verifying the
   zephyr.map files showed the same functions and
   that the flash an ram usage was the same.
