RoleColorEverywhere: Embed/Time/Pronouns support

Before:

After:

Screenshots are made with 70% saturation.

So turns out my last PR #3036 was kinda broken

When trying to re-assign a css var with itself css can't find it!

--text-muted: var(--text-muted) 

will resolve in a black color because of circular dependency, but because we're using color-mix it just mixed our role color with black :)

That's why i'm doing this weird stuff in css, so we don't have circular dependency and colors will resolve as intended

Why changing patch location?

Previous patch was on a too "deep" level of a message, so it could be applied to a normal text, but text inside of embeds will be ignored.
So i've moved it to a message item itself, where MessageLogger and ThemeAtribbutes also have patches

So with both these changes we have:

1. headers/"muted" text are now properly getting colors
2. text inside of embeds also have new colors!
3. As a side effect of moving patch on a upper level it gets applied to a timestamp of a message and for pronouns ( if pronouns db is enabled or how is it called now )

Why use take className from a function call and not apply it imminently

With this approach i'm getting a bug

1. When user doesn't have role/left the server they can't be resolved, so no --saturation and no --role-color which will result it a #000 text!
2. When having potato pc/poor internet connection it can't resolve colors imminently, which also result in a black color for a few ms. Theme-based colors are preferred, so it's better use them while loading

The only thing I don't like is how i'm calling the same function twice, but i have no idea how to reduce it in this example
