Interfaces

[Kronos3]

This PR puts true FPP interfaces in place of our include "../../[...].fppi"

Closes nasa/fpp#702
Depends on nasa/fpp#736

TODO

• Point FPP to the new alpha release once we have it

[Kronos3]

@LeStarch / @bocchino This PR breaks some of the examples since the .fppi interfaces are replaced with true FPP interfaces. Do I need to open a https://github.com/nasa/fprime-examples PR before we merge this to make CI pass? If so how does the CI interaction cross-repo work?

Yes, you should create a PR to the fprime-examples repo with the fix and with following magic prefix in its branch name: pr-3709. That will tell CI here to use the branch there.

@Kronos3 for the fprime-examples CI you likely need to merge the latest fprime-examples@devel in your pr-xxxx branch

[LeStarch]

@thomas-bc when you have a moment, please review w.r.t the com pipeline stuff.

[thomas-bc]

Is there a plan to have a keyword specific to implementing an interface in the future? It's not immediately clear to the reader what import Com does if there's no annotation.
Just a thought, not saying we should add comments everywhere.

[Kronos3]

We are not planning on adding any syntax to denote implementing an interface besides the import. But yes I agree it's not immediately obvious that import is implementing the interface.

Reminder: need to merge nasa/fprime-examples#11 when (ideally right before) merging this PR here.
