nginx: make geoip, image filter optional

Initial goal was to make libgd optional. Because it reduces nginx package size from 109.88 MiB to 41.99 MiB. (Reduction of -67.88 MiB.) GD is a library for the dynamic creation of images.

With libgd:

Without libgd:

Tests runs:

nix build .#nixosTests.{nginx,nginx-auth,nginx-etag,nginx-etag-compression,nginx-globalredirect,nginx-proxyprotocol,nginx-pubhtml,nginx-sso,nginx-status-page,nginx-unix-socket}

Maybe rename it to withImageFilter or withGD?

Although I totally agree with the change, we have to mention this in the release notes. Some users are probably using one of these extensions.

By this point. Which release? (rl-2405.section.md or rl-2411.section.md)

Also, these changes are to a package and not a NixOS module.

Unfortunately, breaking changes are not allowed at this stage of the current release. We should target 24.11.

@fpletz Is the proposed release note acceptable? Thanks for the review.
