Provide method to dump backtrace heap data.
For non-zygote spawned processes, we might want to dump the backtrace
data. Provide a method to send a signal to a process and then dump the
data to a file.
Adds a method to dump the backtrace data on exit.
Update documentation and explain format of heap dump data.
Test: Ran unit tests, enabled new options and used them.
