  Removed common_includes.h reordered includes.
  
  Since we are not using precompiled headers anymore, remove common_includes.h
  so that fewer files are included in cpp files.
  
  Reordered includes to be in the following order:
   1) Local ANGLE project headers, ordered by directory in descending depth
   2) GL headers
   3) STL headers
  This helps enforce the include-what-you-use principal by reducing the
  number of STL headers unexpectedly shared between files.
  
  This include order conflicts with some of the Google c++ style guide
  which states that STL includes should be first but this helps us catch
  more issues.
