models: add md5 support

Browse source 
Has:
 * no hacks for replace md2 with md5 automatically(TODO),
 * no logic for merge anim and mesh content as required by loader(TODO),
 * automaticlly converted md5 to md2 like internal format.

Part of https://github.com/yquake2/yquake2remaster/issues/4

Based on:
 * http://tfc.duke.free.fr/coding/md5-specs-en.html
 * https://github.com/Shpoike/Quakespasm/blob/qsrebase/Quake/gl_model.c (Normals code)

Also looked to:
 * https://github.com/Novum/vkQuake/blob/master/Quake/gl_model.c#L4181
 * https://github.com/fte-team/fteqw/blob/master/engine/common/com_mesh.c

Bonus goals:
* MDL/Quake1 model format support,
* Daikatana model/wal/map format support,
* Load colormap as 24bit color,
* Use shared model cache in client code insted reimplemnet in each render,
* Add debug progress loading code.
* Check load soft colormap as 24bit color,
* Use separete texture hi-color buffer for ui in soft render,
* Convert map surface flag by game type,
* Cleanup function declarations in game save code,
* Support scalled textures for models and walls in soft render and fix
lighting with remastered maps.
Not a goal:
* multiplayer protocol support with KEX engine,
