Prepare 15.0.0 release (#832)

# What does this PR do?

* Bump workspace version to 15.0.0
* Build configuration-ffi by default with the profiling artifacts so we can distribute it in the next release

# Motivation

The major version increase is necessary because of some breaking changes in the crashtracker APIs.
