Martín Lucas Golini b5efd6d709 Graphics: refine drawable cloning and icon source rendering: ...

Rename Drawable::createInstance() to clone() and update drawable implementations,
typed helpers, consumers, tests, tools, and external modules.

Avoid retaining private icon clones for immediate single-threaded rendering in the
code editor and ecode plugins. Borrow cached per-size icon sources instead, restoring
temporary color changes after drawing, while preserving owned clones for widgets,
menus, models, and other stateful consumers.

Reduce common drawable allocation overhead by lazily creating DrawableResource
callback state, using inline callback storage and notification snapshots, and safely
supporting callback disconnection during notification.

Lazily allocate UIImage and UINodeDrawable asynchronous lifetime tokens only when
an uncached asynchronous load is actually scheduled.

Document the distinction between borrowed immediate rendering and independently
owned drawable state.
