The generic helper also has helper code to validate the root element and
create an XPath context. Many places in the code duplicate code for
doing these operations.
Extend the helper to provide all arguments and fix all callers.
In many cases this patch refactors the passing of the 'validate'
field into a separate variable to avoid quirky looking arguments.

only when building QEMU's cmd line. Move it into validation

While this commit is moving the validation to a place that does
not validate all the possible code paths, it's okay, because only
the explicit memory device has user-configurable target node

Normally when an UEFI firmware is marked as read-only, an associated
NVRAM file will be created. Some builds of UEFI firmware, however, wish
to remain stateless and so will be read-only, but never have any NVRAM
file. To represent this concept a 'stateless' tristate bool attribute
is introduced on the <loader/> element.
There are rather a large number of permutations to consider.

Generally speaking, when firmware autoselection is in use we
don't want any information to be provided manually. There are
two exceptions:
* we still want the path to the NVRAM file to be customizable;
* using <loader secure='yes'/> was how you would ask for a
firmware that implements the Secure Boot feature in the
original approach to firmware autoselection, so we want to
keep that working.
Anything else should result in a descriptive error.

This combination doesn't make sense and so the firmware
autoselection logic will not be able to find a suitable firmware,
but it's more user-friendly to report a detailed error upfront.
Note that this check would ideally happen in the validate phase,
but if we moved it there we would no longer be able to
automatically enable secure-boot when enrolled-keys=yes. Since
the combination never resulted in a working configuration, the
chances of this causing real-world VMs to disappear are
