Move HiDPI-related Pepper interfaces to stable
This adds the APIs provided in PPB_View_Dev_0_1 and PP_Graphics2D_Dev_0_1 to
the public Pepper APIs for PPB_View and PPB_Graphics2D.
Includes:
- Change to IDL and generated C headers/shim
- Change to PPAPI to export the 1_1 interfaces
- C++ glue
- Example PPAPI plugin for using HiDPI Pepper APIs
BUG=144071
TEST=Existing (prebuilt) PDF plugin using 1.0 interfaces still works
