Improve reporting of subprocess crashes.

-Split extension renderer crashes out of the existing UMA renderer crash metric 
into its own metric.

-Add a new metric for the sum of all ChildProcessHost crashes.

-Add histograms for each crash type.


BUG=28022
TEST=We should start getting more crash reports in UMA and histograms.
