  CGL: Remove the impl preprocessor guards
  
  Adhere to the project formatting:
  - Remove #if preprocessor guards from the CGL implementation.
  - Order the includes as in style guide
  - Use include / import consistently
  - Move GLES_SILENCE_DEPRECIATION into .gn, similar to CGL
  - Remove or add platform.h include based on whether the file
      itself actually the platform.h defined macros
  
  Simplifies the nested preprocessor macros. Makes it simpler
  to further fix the preprocessor use.
  
  WebKit should instead have a non-ANGLE .mm file #importing
  the implementations with the proper include guards.
  
  Moves macOS specific APIs from SystemInfo.h to SystemInfo_internal.h,
  since common/platform.h is not available for Chrome clients of
  SystemInfo.h
