Currently, the embedded SDK builds the C driver and the C driver extension, then bundles them up, and then takes them apart again for release.

It would be better if the embedded build of the C driver happened in the C drivers evergreen project.

Additionally, we should migrate the embedded C driver extension either into the C driver repository or a new repository, and then build and release it from a process outside of the server. Since the build of the extension depends on the embedded SDK headers, this would need to be a triggered cross-project build.
