Insert temporary input node to polyfill submitter argument in FormData (#26714)

Insert temporary input node to polyfill submitter argument in FormData.
This works for buttons too and fixes a bug where the type attribute
wasn't reset.

I also exclude the submitter if it's a function action. This ensures
that we don't include the generated "name" when the action is a server
action. Conceptually that name doesn't exist.
