scripts: runners: ezflashcli: Add support to flash images for MCUboot

Internal bootloader will only run application image if valid product
header is present on flash. This means product header is required for
application that are not linked to code partition. Other applications
that are linked to code partition are meant to be run by MCUboot and
should not touch product header, with the exception of MCUboot itself
which is also run by internal bootloader so requires product header.

Default flash load offset for applications not linked to code partition
is set to 0x2400 as this is where internal bootloader looks for an
application image to run based on product header written by flasher.

Flash load offset for MCUboot is set from boot partition.

Valid product header is added by ezFlashCLI when using "flash_image"
command.
