Spoike 6e825e42dd merge gl+vk win32 code. include egl support on windows (useful for ANGLE). 
fix misc bugs.
rewrote skeletal code to use gpu-friendly skeletal data for all skeletal formats.
add modelframecount builtin, to easily get the number of frames in a model.
integrate hlmdl a little better.
