AwakePriority virtual property

[microlith57]

this adds an AwakePriority virtual property on Entity, that can be used to change the order that Awake is called, similar to how Depth affects update and render.

• thanks to bit (micycle on codeberg) for the initial implementation!
• thanks to @cloudsbelow for suggesting the virtual property approach (chosen since it doesn't cost memory or performance per entity, while a component or field would)

while I don't believe in a feature necessarily having to supersede a different one, I'm just wondering...
what are your thoughts on the PostAwake event as implemented in #1055?
I'd also appreciate it if you'd review that PR as well - it's been left in the dark for quite a bit

@SilverDorian46 i agree that this serves a very similar purpose to PostAwake, but i think they're different enough to peacefully coexist ^_^
