VFX Optimization Pass

[jilfranco-unity]

Description

This is a PR for an optimization pass done on all of our VFX. This was prompted by seeing how complex our Boss effects were--I wanted to check in on the rest of our VFX to make sure they weren't overly complex. For the most part, we were in great shape! But there were some things I was able to simplify.

Things changed:

• Imp defeat from ~95 particles to ~35
• Imp bomb throw explosion effect materials fixed and effect modified overall to look more convincing
• Slash effects meshes for tank, imp, rogue vert counts reduced by about half
• Archer arrow billboard mesh vert count reduced by 75%
• Lots of trail effects vert counts reduced by about half
• Archer charged arrow effects simplified and modified to make the difference between the 3 tiers more noticeable, charged shot arrow size increased to 1.5 across all 3 tiers to match with regular attack arrow size
• Supporting material edits made as needed
• Typo corrected in one of the mesh names
• Run smoke max particle limit and lifetime reduced some more, as well as particle size reduced slightly from 3 to 2.5 'cause it looked too large imo

Most of these changes are meant to be invisible/have the effects look the same, but be less expensive, but here are some videos of things that have changed visually!

Imp bomb explosion before (most likely these materials got messed up in the port to URP when I re-hooked up all of our materials, but went unnoticed since we don't use this effect in game):

Archer attacks after (using what what already there, I mostly just modified colors, positions, and particle sizes to get the effects I wanted):
