Implement chrome://crashes

Creates a new internal page for listing recent reported crashes, to make it easier for users to report crashes, or get crash IDs when asked in bug reports.

Won't yet display any crashes on Windows, since the breakpad side is not yet done on Windows.

BUG=41106
TEST=Visit chrome://crashes; depending on the build type, platform, and metric pref state, it should display crashes or an informative message.
