Add auto options for all experimental plugins

[JosiahWI]

Auto options were added for the experimental plugins with special dependencies in #10741. This adds options for the remaining experimental plugins.

Blocking on #10968 for the OSX build.

The OSX failure is due to a CMake issue present in master. I discussed it with @cmcfarlen and am working on a fix. Marking this as a draft until then.

This is about ready, but I still have to solve the problem of ImageMagick being used both in both the webp_transform and magick plugins.

It was discussed that it is clearer to have auto_options just set the USE_XXX variables, and put the logic to add the subdirectories in experimental/CMakeLists.txt. I will update the PR with this change at some point.

A CMake issue that caused the necessity for a workaround for ImageMagick is being tracked here: https://gitlab.kitware.com/cmake/cmake/-/issues/25970.

Cherry-picked to v10.0.x

[leontian]

@cmcfarlen auto options for stale_response plugin was not added when cherry-picked to v10.0.x, also missing add_subdirectory(http_stats). These 2 plugins are not built with latest 10.0.x and BUILD_EXPERIMENTAL_PLUGINS=ON

[JosiahWI]

Thank you for reporting, @leontian, those two were indeed missed. I will PR a fix.
