qemu: Make most qemuDomainMachine*() functions static

Ideally we'd make all of them static, but there are a few
cases where we don't have a virDomainDef instance handy and
so they are the only option.

For the few ones we're forced to keep exporting, document
through comments that the alternative is preferred.
