[Mac] The profile name field shouldn't be multi line because that's silly.

[Mac] The profile name field shouldn't be multi line because that's silly.

BUG=424147
TEST=Start Chrome with --enable-new-avatar-menu. In the avatar menu, edit
the profile name and try to press Alt+Enter to get a new line. This
shouldn't work.

Hmm, yeah. I didn't notice any changes. It just blocks Alt+Enter from being a
thing. Is there anything in particular I should look out for?

If you didn't change font size, you should be OK.
