Use the node topology cache and avoid modifying the node tree
in a non-threadsafe way to improve the predictability of using
the helper function. Replaces the implementation from

The `ED_object_get_active_image` is used from the renderer which deals with
evaluated objects. This means the material api for evaluated objects has
to be used.

Related to {D15885} that requires scene parameter
to be added in many places. To speed up the review process
the adding of the scene parameter was added in a separate
patch.

This patch adds edge selection support for UV editing (refer T76545).
Developed as a part of GSoC 2021 project - UV Editor Improvements.
Previously, selections in the UV editor always flushed down to vertices
and this caused multiple issues such as T76343, T78757 and T26676.
This patch fixes that by adding edge selection support for all UV
operators and adding support for flushing selections between vertices
and edges. Updating UV select modes is now done using a separate
operator, which also handles select mode flushing and undo for UV
select modes. Drawing edges (in UV edge mode) is also updated to match
the edit-mesh display in the 3D viewport.
Notes on technical changes made with this patch:
* MLOOPUV_EDGESEL flag is restored (was removed in rB9fa29fe7652a).
* Support for flushing selection between vertices and edges.
* Restored the BMLoopUV.select_edge boolean in the Python API.
* New operator to update UV select modes and flushing.
* UV select mode is now part of editmesh undo.
TODOs added with this patch:
* Edge support for shortest path operator (currently uses vertex path logic).
* Change default theme color instead of reducing contrast with edge-select.
* Proper UV element selections for Reveal Hidden operator.

This is needed since 4d0f846b936c9101ecb76a6db962aac2d74a460a
however change in the operator instead of the event handler is correct,
as accepting a press event should suppress drag events unless
the pass-through flag is set.
This is how select & tweak already works.

Having this setting stored in the image space caused low level selection
logic to have to pass around the image space (which could be NULL
in some cases). Use the tool-settings instead since there doesn't seem
to be much/any advantage in having this setting per-space.

Goals of this refactor:
* More unified approach to updating everything that needs to be updated
after a change in a node tree.
* The updates should happen in the correct order and quadratic or worse
algorithms should be avoided.
* Improve detection of changes to the output to avoid tagging the depsgraph
when it's not necessary.
* Move towards a more declarative style of defining nodes by having a
more centralized update procedure.
The refactor consists of two main parts:
* Node tree tagging and update refactor.
* Generally, when changes are done to a node tree, it is tagged dirty
until a global update function is called that updates everything in
the correct order.
* The tagging is more fine-grained compared to before, to allow for more
precise depsgraph update tagging.
* Depsgraph changes.
* The shading specific depsgraph node for node trees as been removed.
* Instead, there is a new `NTREE_OUTPUT` depsgrap node, which is only
tagged when the output of the node tree changed (e.g. the Group Output
or Material Output node).
* The copy-on-write relation from node trees to the data block they are
embedded in is now non-flushing. This avoids e.g. triggering a material
update after the shader node tree changed in unrelated ways. Instead
the material has a flushing relation to the new `NTREE_OUTPUT` node now.
* The depsgraph no longer reports data block changes through to cycles
through `Depsgraph.updates` when only the node tree changed in ways
that do not affect the output.
Avoiding unnecessary updates seems to work well for geometry nodes and cycles.
The situation is a bit worse when there are drivers on the node tree, but that
could potentially be improved separately in the future.
Avoiding updates in eevee and the compositor is more tricky, but also less urgent.
* Eevee updates are triggered by calling `DRW_notify_view_update` in
`ED_render_view3d_update` indirectly from `DEG_editors_update`.
* Compositor updates are triggered by `ED_node_composite_job` in `node_area_refresh`.
This is triggered by calling `ED_area_tag_refresh` in `node_area_listener`.
Removing updates always has the risk of breaking some dependency that no
one was aware of. It's not unlikely that this will happen here as well. Adding
back missing updates should be quite a bit easier than getting rid of
unnecessary updates though.

Also add calc_normals argument, which will have benefits when

Internally UV selection considered close UV's to be connected.
While this could be convenient in some cases,
it complicates logic for more advanced selection operations that
need to check when UV's should be considered part of the same vertex
since simple threshold checks would give different results depending
on the order of UV's tested.
Users must now run "Merge by Distance" instead of relying
on this selection threshold.

Removing this from UV edit-mode as this wasn't working in any
