cmake: add USES_TERMINAL to show cargo output

[dario23]

Otherwise the CMake output is just stuck at the rust build step for
however long it takes to build.

@d3zd3z this is what should fix the issue we briefly touched on in today's Zephyr Rust status talk; marking it as draft because i can't test with my current environment.

If you get a chance, can you add to the other add custom command block. Also, the commit itself should have a Signed-off-by block at the end. See the other commits for more information. I think Zephyr guidelines also limit the length of lines in the commit text to 75 or so.

[d3zd3z]

Let me know, if you prefer, and I can just pull this change into some upcoming changes I have. I will need to have your full name for the email and the signed-off-by.

Or feel free to update it yourself.

updated; also changed the commit description/first comment here, not sure what ends up in the commits in the end.

I should try to get checkpatch running. @dario23 this is the current output. These should be easy to fix. You'll have to do:

$ git config user.name 'Johannes Schilling'
$ git commit --amend --reset-author

to get it to update the author. The rest are the styling and formatting.

You can use git commit ... -s to add the signed-off-by line automatically (it works with amend).

WARNING: Missing Signed-off-by: line by nominal patch author ''

total: 0 errors, 3 warnings, 14 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
      mechanically convert to the typical style using --fix or --fix-inplace.

Your patch has style problems, please review.

NOTE: If any of the errors are false positives, please report
      them to the maintainers.

It is complaining that the author doesn't match the signed off by (which can be fixed with the reset author), and about the capital O and B in the Sign-off-by.

Looks OK to me - from what I gather, this should show incremental build progress as the rust compiler builds sources, right?
