Fix a crash which occurs in the Win32K lockdown mode in the renderer process.

The crash occurs because of code in WebKit attempting to get the system font metrics which fails in the Win32K lockdown mode.

Proposed fix is to pass the font name and height for the system fonts to the renderer process and cache them
there. We only need these two values for now.

This is the browser side of the change. The renderer side change to cache this information for WebKit will come along in a subsequent patch.
