Missing KaiMei qualifiers

BUR #37351 has been approved by @evazion.

rename kaito_(sp) -> kaito_(sp)_(vocaloid)
rename meiko_(sp) -> meiko_(sp)_(vocaloid)

The PRSK tags are probably fine without because of their format but these definitely need qualifiers.

BUR #37388 has been approved by @evazion.

create alias kaiko -> kaiko_(vocaloid)
create alias meito -> meito_(vocaloid)

Feel like these could probably also stand to have qualifiers.
