CSE Machine: Fix some UI & animations issues, and add tests

[CZX123]

Description

This PR fixes some UI & animations issues, and add some tests for the CSE machine's layout and animations.
Fixes #2921 fully by correctly calculating the width of the frame with a rune.
Fixes #2959.
Fixes #2716. The new result is shown below:

Changes

UI

• Improved environment frame positioning, spacing is now more consistent.
• Global frame default text of :::pre-declared names::: now should appear first, above all bindings
• Arrows from arrays now always exit the array first before pointing to their targets.
  • If the arrow comes from the first unit of the array to itself, it will now form a circular loop
    
• Changed height and width behavior for array and function values
  • _height and _width now only refer to the height and widths of the array boxes or closure circles only
  • ArrayValue now has a totalHeight and totalWidth property that stores the total height and width of nested values inside the array
  • FnValue and GlobalFnValue has a totalWidth property that also includes the tooltip width
• Double quotes are used for strings in the stash now.

Animations

• Fixed frame arrows not animating alongside the frame creation in FrameCreationAnimation
• Fixed the animation function inside BaseAnimationComponent, so that the example below has the correct expected behavior:

  a.animateTo({ x: 100 });
  a.animateTo({ x: 200 }, { delay: 1 });

Testing

• Add test cases for the CSE machine's layout for values
• Add test cases for the CSE machine's AnimationComponent

@sayomaki do you have time to review this? It's a pure FE change and the PR seems ready, I don't see a reason not to merge it if it's all good
