Global @keyframes animations

[kof]

Allow creating global @keyframes animations. We already have the UI for that we can reuse, which is currently only available on Animation Group component.

Todo

• Allow adding keyframes from Global root
• Reuse the UI for Keyframes used on Animation Group component
• Ensure animation names are unique
• Allow referencing the animation name from animation/animation-name properties in advanced style panel
• Use keyframes animation to provide default animations on Radix Accordion, Dialog and all other components, you can find the definitions on shadcn or radix documentation
• Maybe retire ani-motion by making sure everything it does is already either built-in or is in the main section components library on the marketplace
• Make sure pasting style tag with keyframes doesn't create html embed but uses style sources
