This separates token generation code to be more
modular. Depending on the context, individual
parts of the code need to be placed in different
locations.

Two major refactors are the change of macro input
as well as moving module generation out of the
struct definition generation.

This commit doesn't include changes for enum
generation. This will be done in a separate commit.

This commit contains a major rework of most parts of the attribute
macro to support attaching it to modules. Most of the previously
existing features are already in place. There are only two missing
features which will be added in follow-up commits: version specific
doc comments and merged CRD YAML support. Because of that, some
snapshot tests are failing.

This also adds a test to validate that the relevant code is not
generated of the skip option is set.
