    c++: diagnostic for template placeholder in parm [PR106793]

    Talking about the declarator form doesn't help when fixing that would get
    you a different error about placeholders not being valid in a parameter.

    This also adds a <> fixit, which isn't enough for most templates, but is a
    start.
