Implement HiDPI support in Pepper dev interface
This patch requires WebKit patch https://bugs.webkit.org/show_bug.cgi?id=87874 (WebKit r121364)
Expose device_scale_factor and css_scale_factor to Pepper plugins via a dev
interface on View resource.
Allow Pepper plugins to create a 2D graphics context with a scale factor so the
plugins can render at device resolution rather than DIPs if they want.
BUG=114673
TEST=browser_tests --gtest_filter="PPAPITest.*"
TEST=browser_tests --gtest_filter="OutOfProcessPPAPITest.*"
TEST=Build, run existing PPAPI plugin at 2x scale
TEST=Build, run test HiDPI aware plugin to render at device rez, at 1x, 2x scale
