We can finally introduce a specific target model for the spapr-vty
device used by pSeries guests, which means isa-serial will no longer
show up to confuse users.
We make sure migration works in both directions by interpreting the
isa-serial target type, or the lack of target type, appropriately
when parsing the guest XML, and skipping the newly-introduced type
when formatting if for migration. We also verify that spapr-vty is
not used for non-pSeries guests and add a bunch of test cases.

This attribute was used to decide whether to format the type
attribute of the <target> element, but the logic didn't take into
account all possible cases and as such could lead to unexpected
results. Moreover, it's one more thing to keep track of, and can
easily fall out of sync with other attributes.
Now that we have VIR_DOMAIN_CHR_SERIAL_TARGET_TYPE_NONE, we can
use that value to signal that no specific target type has been
configured for the serial device and as such the attribute should
not be formatted at all. All other values are now formatted.
