lots of seemingly unrelated changes

[khancyr]

yes, it needs #6118 first as we got some recursive dependences. Current Sphinx build don't catch it but the new version is catching it.

most of the files changed in this PR bear no relation to the title or stated intention in its description...please separate into a different PR

[khancyr]

It needs the recursion fix PR otherwise it won't build and the two other PR. So this one should be the latest merged

[rmackay9]

@khancyr I think maybe it would be good to remove the commit that is already included in #6118

[Hwurzburg]

@khancyr have you tested this thoroughly?

[khancyr]

I have build all wikis without issues reported.
I have check manually that each a opening and open random pages : No visibles diff with the current version, images are at same place and video too.
So that seems pretty safe.

For the build, it correct a bunch of issues and allow to build a bit faster this we can now disable some options that weren't used in our build !

Still need to be merged after the recursion , Youtube-contrib and theme update PRs, all three are needed to allow build with the new version.
