Zack TannerandGitHub ccfe67aa8d Return 200 for client-handled Server Action redirects (#96310) ...

## Summary

Client-handled Server Action redirects currently return a `303` without
a `Location` header and may include a streamed RSC response body. Some
HTTP intermediaries reject this response or strip its body because it
looks like an HTTP redirect.

Return `200` for client-handled Server Action redirects while continuing
to use `x-action-redirect` and the RSC response. Progressive-enhancement
form submissions still return a standards-compliant `303` with
`Location`.

Fixes #92882
Fixes #74026
