vmx: add VIR_DOMAIN_DEF_FEATURE_NO_BOOT_ORDER

Further patches will introduce validation and a default setting
of def->os.bootDevs in postParse.

Introduce a feature flag to opt out of this and set it in the vmx
driver, otherwise we would be adding it <boot dev='hd'/> into every
vmx config despite having no way to change it.
