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 since 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.
