Several of the Elezen mobs in Stone Vigil HM also turn into dragons if you don't kill them fast enough. Though to be honest, all the NPCs calling it a 'glamour' confuses me as to whether this process is just an illusion or an actual physical transformation. Can all heretics of a certain 'rank' do this? Is it an ability that dragons bestow on them through some kind of magical means?

Yes, that's where i get confused to. We don't see a dragon to human shift, just humans to dragons using the power 'dragons blood'. Which... could mean anything. Really, when I saw that, I thought it was a reagent, like a vial of dragons blood, that the cultists where consuming to gain power.
