[6.0.x] Fixed #36743 -- Increased URL max length enforced in
HttpResponseRedirectBase.
Refs CVE-2025-64458.
The previous limit of 2048 characters reused the URLValidator constant
and proved too restrictive for legitimate redirects to some third-party
services. This change introduces a separate `MAX_URL_REDIRECT_LENGTH`
constant (defaulting to 16384) and uses it in HttpResponseRedirectBase.
Thanks Jacob Walls for report and review.
Backport of a8cf8c292cfee98fe6cc873ca5221935f1d02271 from main.
