gyaru_v utility aliases

BUR #14372 has been rejected.

create alias upside-down_v -> gyaru_v
create alias reverse_v -> gyaru_v

For discoverability

post #5971917, post #5956367, post #5930796. They are upside-down_v, but aren’t gyaru_v.
Upside-down_v involves gyaru_v with other v_pose.

post #5972669, post #5969924, post #5968668, post #5967163 and post #5930796 again. These posts are reverse(front/back) v, but we can’t call them gyaru_v

And reverse_v involves both of front/back and up/down. So this tag is not related with gyaru_v

BUR #14414 has been rejected.

remove implication gyaru_v -> v
