chore: Refactor Entity#TryAttack/Attack and its variations

[AlexVild]

Description

The whole flow for attacking is an absolute nightmare to nagivate/expand upon, whether via melee, spells, or projectiles.

It could/should be much simpler/fragmented, and it would benefit further modification greatly to get it all squared away.

Intended Use-Case

Improve future code modifications by simplifying code base and limiting massive "omni" functions in the player.
