Fix T94464: video texture is not refreshing

In the past that worked because the `GPUMaterial` referenced the
`ImageUser` from the image node. However, that design was incompatible
with the recent node tree update refactor (rB7e712b2d6a0d257d272e).
Also, in general it is a bad idea to have references between data that is
owned by two different data blocks.

This incompatibility was resolved by copying the image user from the node
to the `GPUMaterial` (rB28df0107d4a8). Unfortunately, eevee depended
on this reference, because the image user on the node was update when the
frame changed. Because the image user was copied, the image user in the
`GPUMaterial` did not receive the frame update anymore.

This frame update is added back by this commit. The main change is that
the image user iterator now also iterates over image users in `GPUMaterial`s
on material and world data blocks. An issue is that these materials don't
exist on the original data blocks and that caused the check in
`build_animation_images` in the depsgraph to give the wrong answer.
Therefore the check is extended.

Right now the check is not optimal, because it results in more depsgraph
nodes than are necessary. This can be improved when it becomes cheaper
to check if a node tree contains any references to a video texture.
The node tree update refactor mentioned before makes it much easier
to construct this kind of run-time data from the bottom up, instead of
scanning the entire node tree recursively every time some information
is needed.

Fix T94416: incorrect handling when nodes are linked in a loop

This just skips the entire algorithm when there are cycles.
In the future, cycles could be handled more gracefully in the
algorithm, but for now that's not worth it and is not necessary
to fix the bug.

Fix (unreported): missing relations update after adding scene time node

This just moves the relations update to a lower level function that is used
by other functions. Eventually, the special case for this node should be
generalized.

Fix T94408: missing sockets after adding node group

Cleanup: clang tidy

Use c++ headers; use nullptr; redundant `void` in parameter list;
inconsistent parameter name.

Render: move editor/render module to c++

Doing this in preparation for some work on asset preview generation.
