  Apply Chromium style fixes.
  
  This addresses several minor code quality issues that are validated
  in Chromium, but not yet applied to ANGLE:
  
  * constructors and destructors must be defined out-of-line
  * auto is not allowed for simple pointer types
  * use override everywhere instead of virtual
  * virtual functions must also be defined out-of-line
  
  Slightly reduces binary size for me (~2k on Win, 150k on Linux).
