feat(codex-ui): popup and confirm implementation

[elizachi]

Added popup and confirm components

• Popup can be called by showPopup() function
• A showPopup() function can be added to any component, for example with @ click
• You can also embed any component in the popup itself using showPopup() with component and props parameters
• As an example, a new confirm component was embeded into the popup
• The window can be closed using the optional close button
• When you click on the confirm buttons, you can trigger any events, passing them to the confirm as on-close-activate and on-confirm-activate
