android: Add ChildProcessCrashObserver.java

ChildProcessCrashObserver.java serves a similar purpose as
CrashDumpManager.java did (which it will replace), except without the
need (or ability) to check for a minidump on the filesystem. Instead of
a minidump path, the process ID of the crashed child is passed to the
callback which it can use to identify the correct crash dump.
