When generating an image with trailer (--pad or --confirm), the
imgtool also adds the erased values into that area. This is not
wanted for flash drivers which use ECC and treat writing erased
values as a real write action, which cannot be overwritten anymore.

The value of `--max-align` parameter passed to imgtool can never be
less than the value of `--align` parameter. At present the default
value of `--max-align` is fixed at 8. This forces user to pass the
parameter even when its value can be safely inferred.

Change the default value of the `--max-align` parameter to the larger
of the two values: `--align` or 8. Consequently, the user is required
to pass the parameter only if the flash alignment of the primary and
secondary slot differ.

Instead of trying to main two test runners for the Zephyr sample
directory, have the old test runner just print out a message that users
should use the new test runner.  Eventually, we can just remove old
runner entirely.

Instead of asking the user for each test if it worked or not, the new
test runner looks at the serial log and makes this conclusion itself.
It is able to run the whole test suite completely automatically.

This change is to avoid misunderstanding as IDF is not supported
on top of MCUboot.
The Espressif port acts as a bare metal bootloader that can be
used on Espressif chips to boot supported OSes (like Zephyr or NuttX).
