Cleanup: Remove seq->tmp_flag DNA member

Commit f0d20198b290 used this field to flag rendered strips which were
queried by `SEQ_query_rendered_strips()`. Then operators iterate all
strips and checks state of `seq->tmp_flag`.

Use collection returned by `SEQ_query_rendered_strips` directly.
There should be no functional changes.

This commit adds functions `all_strips_from_context` and
`selected_strips_from_context` that provide collection of strips based
on context. Most operators can use this collection directly.
There is already `seq->tmp` DNA field, but is should not be used unless
absolutely necessary. Better option is to use human readable flag.
Best is to not use DNA fields for temporary storage in runtime.

Add layer and pass index parameters to rna_Image_gl_load

This patch adds a layer_idx and pass_idx parameter to the rna_Image_gl_load function. It exposes both to the Python API as optional parameters.
This allows python scripters to specifiy which layer and pass they want to load in to an OpenGL texture. Right now image.gl_load() always takes the first layer and first pass.
This is limiting when working with multilayer openEXRs.

With this patch scripters can do something like this:

```
pass_idx = area.spaces.active.image_user.multilayer_pass
layer_idx = area.spaces.active.image_user.multilayer_layer
image.gl_load(frame=0, layer_idx=layer_idx, pass_idx=pass_idx)
```

As the parameters are optional and default to 0, it should not break existing code.

Cleanup: Store instances id attribute with other attributes

Now that we can store any dynamic attribute on the instances component,
we don't need the special case for `id`, it can just be handled by the
generic attribute storage. Mostly this just allows removing a bunch
of redundant code.

I had to add a null check for `update_custom_data_pointers` because
the instances component doesn't have any pointers to inside of
custom data.

Geometry Nodes: Generalized Compare Node

Replace compare floats node with a generalized compare node. The node
allows for the comparison of float, int, string, color, and vector.

The datatypes support the following operators:
Float, Int: <, >, <=, >=, ==, !=
String: ==, !=
Color: ==, !=, lighter, darker
(using rgb_to_grayscale value as the brightness value)

Vector Supports 5 comparison modes for: ==, !=, <, >, <=, >=
Average: The average of the components of the vectors are compared.
Dot Product: The dot product of the vectors are compared.
Direction: The angle between the vectors is compared to an angle
Element-wise: The individual components of the vectors are compared.
Length: The lengths of the vectors are compared.

Geometry Nodes: Dual Mesh Node

This node calculates the dual of the input mesh. This means that faces
get replaced with vertices and vertices with faces. In principle this
only makes sense when the mesh in manifold, but there is an option to
keep the (non-manifold) boundaries of the mesh intact.

Attributes are propagated:
- Point domain goes to face domain and vice versa
- Edge domain and Face corner domain gets mapped to itself
Because of the duality, when the mesh is manifold, the attributes get
mapped to themselves when applying the node twice.

Thanks to Leul Mulugeta (@Leul) for help with the
ascii diagrams in the code comments.

Note that this does not work well with some non-manifold geometry,
like an edge connected to more than 2 faces, or a vertex connected to
only two faces, while not being in the boundary. This is because there
is no good way to define the dual at some of those points. This type
of non-manifold vertices are just removed for this reason.

Geometry Nodes: deduplicate join geometry code

The Realize Instances and Join Geometry node can share most of their code.
Until now, both nodes had their own implementations though. This patch
removes the implementation in the Join Geometry node in favor of the more
general Realize Instances implementation.

This removes an optimization for avoiding spline copies. This can be brought
back later. The realize instances code has to be rewritten to support attribute
instances anyway.

Cleanup: Fix errors in previous commit

After 1ef8ef4941dd there were build warnings because of unused
arguments. Also missed to change code to iterate `strips` instead of
`seqbase` in 2 functions.

Fix: Instances component does not copy attributes

Fix: Remove incorrect asserts for empty attributes

While it is an edge case, it isn't incorrect for the attribute storage
to have a zero size, it will just return an empty span or nothing.

LineArt: Fix consistent view vector bug from merging.
