Martín Lucas Golini dc377335b9 graphics: migrate drawables to shared ownership ...

- introduce DrawablePtr and per-consumer createInstance() semantics
  - add TextureDrawable wrappers backed by shared TexturePtr handles
  - migrate regions, sprites, nine-patches, state lists, skins, groups, gradients,
    UI widgets, tools, modules, ecode, and eeiv to shared drawable ownership
  - remove ownIt flags, manual drawable deletion, and unload-based lifetime handling
  - replace drawable callback IDs with RAII change connections
  - move Variant drawable storage outside its scalar union
  - split UIIcon source lookup from explicit drawable instance creation
  - retain icon instances used by rendering loops instead of cloning per frame
  - avoid shared source mutation in texture-region consumers
  - use drawable type tags instead of RTTI casts
  - fix nearest-size UIIcon lookup
  - document the drawable source/instance contract and add ownership tests
