trying to use spirv_to_dxil from mesa3D, following script extracts neccessary source code from mesa3d repo

@echo off

REM this script copy parts of mesa we use, so users don't have to clone whole mesa

REM clone mesa repository next to LumixEngine directory
REM needs python3
REM need pyyaml and mako module installed 
REM pip install pyyaml
REM pip install mako

REM call :gen
call :copySources
goto :eof

REM copy only necessary stuff from mesa repository
