[examples] Several fixes and improvements (#6042)

Browse source 
* models_loading_iqm - actually use animIndex

* models_decals - fix button placement

* core_highdpi_testbed - unrelated TODO

* audio_sound_positioning - fix SetSoundPosition and panning

* SetSoundPan is clamped already

* remove version check

* fix 'updated with' in the header
