[Shadow] APL improvements banking Void Volley and pooling insanity for VF

[Urcra]

Small improvement to spriest APL

One change is when we get closer to voidform we can try to save up a bit of insanity as long as we keep the same SWM uptime casting SWM inside of voidform will be more dmg and will also slightly extend VF

Second change is that since the void volley buff from our 4pc has such a long duration we are in no rush to spend it as soon as we get it, and could wait to spend it at a better time, for archon this means trying to spend them inside our resonant energy buff. For VW the dps increase mainly seems to come from deprioritizing it which makes us cast some more SW:D on execute.

The insanity pooling is only a dps increase on ST as with more targets it seems better to just cast it and thus have higher spread uptime on it. So I had to add some extra clauses to avoid it regressing the dungeon slice sim mainly the target.time_to_die<25|active_enemies>1
