[Fizz] Fallback to client replaying actions if we're trying to serialize a Blob (#28987)

This follows the same principle as in #28611.

We cannot serialize Blobs of a form data into HTML because you can't
initialize a file input to some value. However the serialization of
state in an Action can contain blobs. In this case we do error but
outside the try/catch that recovers to error to client replaying instead
of MPA mode. This errors earlier to ensure that this works.

Testing this is a bit annoying because JSDOM doesn't have any of the
Blob methods but the Blob needs to be compatible with FormData and the
FormData needs to be compatible with `<form>` nodes in these tests. So I
polyfilled those in JSDOM with some hacks.

A possible future enhancement would be to encode these blobs in a base64
mode instead and have some way to receive them on the server. It's just
a matter of layering this. I think the RSC layer's `FORM_DATA`
implementation can pass some flag to encode as base64 and then have
decodeAction include some way to parse them. That way this case would
work in MPA mode too.
