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.
