refactor: refactor the style-layer-list for layers based sections in style-panel

[JayaKrishnaNamburu]

Description

This PR refactors the values in style-panel that handles complex values. Properties like box-shadow, text-shadow, filter, backdrop-filter, transition handles multiples values which needs to be displayed as list. And then allow users to edit them using a content panel. This PR removes all the individual layers of each property and created a common layer list item.

Steps for reproduction

1. Add values to all the sections,
2. Re-order the layers between the values of each property.
3. Deploy / Export the project.

Code Review

• hi @kof, I need you to do
  • conceptual review (architecture, feature-correctness)
  • detailed review (read every line)
  • test it on preview

Before requesting a review

• made a self-review
• added inline comments where things may be not obvious (the "why", not "what")

Before merging

• tested locally and on preview environment (preview dev login: 5de6)

• can't add 2 text shadow layers, adding second deletes the first

[kof]

• backdrop filter is still in the advanced panel by default, needs to be removed, we only have there things by default which are not in the base panel

Will take a look, i actually managed to add multiple of them in local 🤔

[kof]

now text-shadow works now, must have hit something special
