Nadro/adhoc/center rectangle

[nadr0]

closes https://github.com/KittyCAD/modeling-app/issues/4402

Implements

• Used the placeholder we have for Center Rectangle in the toolbar and updated it with the new state
• Implemented a workflow similar to Rectangle but for Center Rectangle
• Center Rectangle is enabled in the rectangle dropdown menu
• Several type narrowing functions for different expressions
• Fixed createLiteral definition since it didn't actually use the type LiteralValue

Gotchas

• Toolbar UX issue are apparent in this ticket but the work will be done in https://github.com/KittyCAD/modeling-app/issues/4469
• We are using the same modtifyAST for rectangle for center rectangle
• Once the center rectangle is created, it edits as if it is a rectangle not a center rectangle due to the handler
• The initial point the user clicks is "wrong" in the KCL code within the startProfileAt but once they click into the second state for dragging the width and height it will be corrected since there is dimension to the box. It effectively says the startProfile at is the center with width/height of 0.

Future improvements

• Do we need a kcl standard library call for center rectangle?
• Do we need a new handler for center rectangle so it only allows center point moving and matched dimensions dragging for height and width?
