[crashtracker] Add option to collect symbols in process

[danielsn]

What does this PR do?

Restores the option to collect symbols in process that was removed in #401

Motivation

I removed it because I thought nobody was using it. Turns out Python was. Putting it back in.

Additional Notes

Anything else we should know when reviewing?

How to test the change?

Modified crashtracker.c to use the new enum, and got this output
