[flang] Add team_type to num_images intrinsic call

[ktras]

Summary

num_images had previously been added to the list of intrinsics
before the type team_type had been implemented. Now that team_type
is implemented, add the num_images call that has the team argument.
Update the semantics tests for num_images.

It looks like this comment should go away.

• In the semantics test, remove section of comment that says "not yet supported" when referring to the team argument
• Fix the formatting in the changes in flang/lib/Evaluate/intrinsics.cpp after running git clang-format

Thank you for catching that! I have now removed the "not yet supported" part of that comment.

Looks good to me.

I don't have push permissions, so if there is no more feedback on this differential, can someone push this to main for me please?
