    c++: static lambda in template [PR108526]

    tsubst_lambda_expr uses build_memfn_type to build a METHOD_TYPE for the=
 new
    lamba op().  This is not what we want for a C++23 static op(), but sinc=
e we
    also use that METHOD_TYPE to communicate the closure type down to
    tsubst_function_decl, let's wait and turn it back at that point.
