    c++: Handle SPLICE_SCOPE in cp_walk_subtrees [PR123659]

    SPLICE_SCOPE is a TYPE_P, but didn't have its SPLICE_SCOPE_EXPR
    walked by cp_walk_tree, so the following testcase has been rejected
    because it didn't find a pack in it.

    SPLICE_EXPR is fine, as it is tcc_expression and walk_tree by default
    walks all the tcc_exception operands for unknown trees.
