@lucasmcdonald3 If you have the time, it would be great to also add Python to the clean recipe.
For example, right now, when ever I need to re-polymorph the MPL, I run:

gmake clean;
rm -rf runtimes/python/src/aws_cryptographic_material_providers/smithygenerated

It should be straightforward to add the rm -rf of the Python Smithy generated to the Makefile.

Putting this PR on ice until Go gets merged.

This would create hiccups for Go that, ideally, we'd avoid for now.

Changes look good, but let's wait till we have Go fully merged and has CI, which should be this week.

Keeping this unmerged until Go ESDK is released.
The breaking change to the Makefile variables would cause a hiccup for Go, and we'd prefer to keep that moving at full speed.
