    openmp: Ensure copy ctor for composite distribute parallel for class
iterators is instantiated [PR95197]

    During gimplification omp_finish_clause langhook is called in several
places
    to add the language specific info to the clause like what default/copy
ctors,
    dtors and assignment operators should be used.

    Unfortunately, if it refers to some not yet instantiated method, during
    gimplification it is too late and the methods will not be instantiated
    anymore.  For other cases, the genericizer has code to detect those and
    instantiate whatever is needed, this change adds the same for
    distribute parallel for class iterators where we under the hood need
    a copy constructor for the iterator to implement it.
