[Feat|Fix|Improvement] (All): Continue building the basic structure.

Feat: implement MG_Impl/Buffer Feat: implement MG_State/ErrorState and integrate it into MG_State/GLContext Feat: add buffer deletion management Feat: introduce `INSERTION_POINT` (https://github.com/MobileGL-Dev/MobileGLCodeManager) Feat: add tests about MG_Impl/Buffer and buffer deletion feature Feat: add several converters Fix: fix some compiling errors Fix: fix some incorrect behaviors in MG_State/Buffer Improvement: remove some current statements at the beginning of the source file, which will be added uniformly soon Improvement: optimize some naming
