[crashtracker] Names for SI_CODEs

[danielsn]

What does this PR do?

Adds best effort code to support translating numeric si_code into human readable names.

Motivation

Every different platform has different mappings of numeric codes to meanings. This saves time on the user to figure out what the code actually was.

Additional Notes

This is a best effort code: It currently doesn't handle signals we don't expect to receive. In that case, it soundly says "UNKNOWN".

OSX POSIX support is the worst: https://vorner.github.io/2021/01/03/dark-side-of-posix-apis.html

How to test the change?

Existing additional tests.

Wonderful! Just to reaffirm, the numerical relationship between si_code concepts and values is underdefined at the POSIX level, but needs to be a part of the stable API provided by a platform.

Usually (Linux, at least), if there are changes to this type of thing, it tends to be additive, so the risk factor is missing the naming of an si_code if our build-time kernel version is less than the runtime kernel version. In practice, si_code is not frequently changed.
