Fix mesh artifacts on vanilla/TBC M2 models when using expansion overlays

Browse source 
Vanilla (v256) and TBC (v263) M2 files embed skin data directly, parsed
during M2Loader::load(). The code unconditionally loaded external .skin
files afterwards, which resolved to WotLK-format .skin files (48-byte
submeshes) from the base manifest — overwriting the correctly parsed
embedded skin (32-byte submeshes) and causing mesh corruption on all
character models. Guard all 13 loadSkin() call sites with version >= 264
so external .skin files are only loaded for WotLK M2s that need them.
