Expose individual module enable/disable in `include/oscc.h`

[shnewto]

Proposed feature or changes

As a user I'd like to be able to enable and disable individual modules independently. As it stands now,
I'm only able to enable and disable all modules at once without digging into functionality defined and wrapped in src/internal/oscc.h.

Use case

I would like to incorporate functionality that enables and disables individual modules into a project
that uses the OSCC API. By exposing the symbols for each module's enable and disable commands in the include/oscc.h I would be enabled to do that.
