virtualx-engine/scene/2d/skeleton_2d.cpp
reduz 6631f66c2a Optimize StringName usage 
* Added a new macro SNAME() that constructs and caches a local stringname.
* Subsequent usages use the cached version.
* Since these use a global static variable, a second refcounter of static usages need to be kept for cleanup time.
* Replaced all theme usages by this new macro.
* Replace all signal emission usages by this new macro.
* Replace all call_deferred usages by this new macro.

This is part of ongoing work to optimize GUI and the editor.
