Migrate lua from 5.1~5.3.x to 5.4.x

[aismann]

• unpack, pack moved from global to package table
• math.pow was removed, use operator ^ instead
• Use # instead table.getn
• Since lua-5.1 math.mod was renamed to math.fmod, the behavior same with operator %
• Remove any garbage collection settings in lua code

I have run the lua-tests project with lua5.4.2, the performance is very slow when scroll the main menu panel, so it may needs a long time to determine whether upgrade to lua5.4.x

Note: By profile with visualstudio, it may caused by incorrect gc mode set

Actually, axmol support simply switch plain lua version with follow steps:

1. unzip lua-5.4.3.tar.gz and copy folder lua-5.4.3 to thirdparty/lua/plainlua/
2. Add "-DLUA_VERSION=5.4.3" when use cmake to generate project files
