lua: generate bindings for Sprite3DMaterial

[Glidos]

Add Sprite3DMaterial to the list of classes for autogeneration of
lua bindings.

Add a new test case to the end of Sprite3DTest.lua showing the
use of outline.material

[minggo]

Error happened when running the test case on Mac:

cocos2d: ERROR: 0:15: 'precision' : syntax error: syntax error

cocos2d: ERROR: Failed to compile vertex shader
[LUA-print] ASSERT FAILED ON LUA EXECUTE: invalid shader
stack traceback:
    [string "Sprite3DTest/Sprite3DTest.lua"]:1342: in function 'onEnter'
    [string "Sprite3DTest/Sprite3DTest.lua"]:1318: in function <[string "Sprite3DTest/Sprite3DTest.lua"]:1316>

And i think you can reuse resources in /tests/cpp-tests/Resources/Materials.

[Glidos]

Okay, I've changed the test to use outline.material and simplified the test in other ways.

[minggo]

@Glidos thanks, you don't have to update files in cocos/scripting/lua-bindings/auto. These files will be auto-generated.

[Glidos]

@minggo okay, autogenerated files removed. So how does that work? I notice the autogenerated files do end up committed to the repo. Is it part of the commit hook?

[Glidos]

So without the autogenerated changes, the test build now fails. I'm confused.

[Glidos]

Oh, and now it's passed. Okay, looks ready to go now.

[minggo]

@Glidos the CI will generate binding codes automatically when checking a PR.

@minggo thank you
