core: introduce animation manager and animation config

[PaideiaDilemma]

This PR uses AnimationManager and AnimatedVaraible from hyprutils to implement an animation system.
Simplifies adding and implementing existing animations.

Before adding the animation manager, it made sense to move all the colors to hyprgraphics using the same wrapper (CHyprColor) that hyprland uses.

There is a bit of code that is basically the same as in hyprland:

• Bezier and Animation config parsing
• Updating variables
• CHyprColor

The config for beziers and animations works the same as in Hyprland. This is the animation tree i came up with:

global
  ↳ fade
    ↳ fadeIn - hyprlock fades in
    ↳ fadeOut - hyprlock fades back to your desktop 
  ↳ inputField
    ↳ inputFieldColors - fade between colors (supports outer gradient, previously fail_transition)
    ↳ inputFieldFade - fade_on_empty animation
    ↳ inputFieldWidth - adaptive width animation
    ↳ inputFieldDots - fade in/out for individual dots in the input field (previously dots_fade_time)

BREAKING:

• Removed input-field:dots_fade_time. Now configured via
  animation=inputFieldDots,...
• Removed input-field:fail_transition. Now configured via
  animation=inputFieldColors,...
• Removed general:no_fade_in and general:no_fade_out. Now configured
  globally via animations:enabled or via animation=fadeIn,... and
  animation=fadeOut,...

NEW:

• Animations can be globally disabled/enabled with animations:enabled

Closes #610
Closes #566
Closes #254

do we want to wait until we also land the tree stuff in hyprutils?

However you prefer, I have the code.

I hate reviewing long MRs

anyways looks alright if it works and doesnt have a backdoor lgtm

most of the code is stolen from hyprland anyways

[PaideiaDilemma]

Understandable.
Yeah lots of stolen Hyprland code in hyprlock 👀

I am running this since yesterday and hope some people from the discord will test it as well.

Works well for me. @alba4k also did not have any problems.
Just bumped the hyprutils version in CMakeLists in the last commits.
