Create Arius student subtags

BUR #53211 has been rejected.

mass update favgroup:50813 -> arius_student_(gl)_(blue_archive)
create implication arius_student_(gl)_(blue_archive) -> arius_student_(blue_archive)
mass update favgroup:50814 -> arius_student_(smg)_(blue_archive)
create implication arius_student_(smg)_(blue_archive) -> arius_student_(blue_archive)
mass update favgroup:50849 -> -arius_student_(blue_archive) char:angel_of_the_apocalypse_(blue_archive)

Arius Student (smg) has short hair with messy bangs and uses a CZ Scorpion Evo 3 submachine gun.
Arius Student (gl) has long twintals with blunt bangs, wears a bulletproof vest and uses a Milkor MGL grenade launcher.
Angel of the Apocalypse (黙示録の天使) is an NPC that was not yet revealed on global and does not have an official English name.
Generic Arius Student needs to remain because there are images depicting them with either ambiguous or unusual designs.

I think this is fine, but I don't think we need an umbrella tag for them.
