[orx-shapes] Add place function and demo for rectangle placement

Introduce `Rectangle.place` to position rectangles dynamically within bounds using anchor points. Added a demo (`DemoRectanglePlace01`) showcasing a 10x10 grid of rectangles evenly distributed across the canvas.

+ * Demo for rendering a 10x10 grid of rectangles within the bounds
+ * of the canvas. Each rectangle's position is calculated relative to its anchors, filling the entire
+ * canvas with evenly placed items.
+ *
+ * The rectangles are drawn using the default white color. The `place` function is applied to each
+ * rectangle to position them dynamically based on their relative anchor points within the bounding area.
+ *
+ * This serves as a demonstration of positioning and rendering shapes in a structured grid layout.
