UI: enable the depend-on-cursor flag for some operators

- Bend (Transform).
- Extrude to Cursor.
- Lasso Select (related operators such as node-cut links, mask.. etc).
- Rip Mesh / UV's.
- Vertex/Edge Slide.

UI: expose "Lasso Select" & "Extrude to Cursor" in menus

- Show "Lasso Select" in menus (along with Box & Circle select)
- Show "Extrude to Cursor" (along with other extrude actions).
- Rename operators that add/extrude on Ctrl-Click
since their names were inconsistent.

This is mainly for discoverability.

Fix: Nodes modifier ignores input value with new property missing

An issue with the previous commit-- the default value of the type was
used instead of the property value when the "use_attribute" property
was missing.

Geometry Nodes: Add a toggle to use attributes as input values

This adds a toggle to node group inputs exposed in the modifier to use
an attribute instead of a single value. When the toggle is pressed, the
button switches to a text button to choose an attribute name. Attribute
search isn't implemented here yet.

One confusing thing is that some values can't be driven by attributes
at all, like the size of a primitive node. In that case, we should have
a node warning, but that will be separate since it's more general.
We can also have an option to turn off this toggle in node group
input settings.

The two new properties for each input are stored with the same name
as the value, but with `"_use_attribute"` and `"_attribute_name"``
suffixes. The properties are not added for socket types that don't
support attribute input, like object sockets.

UI: Automatic Blend Thumbnail Selection

Adds an "Auto" option to blend thumbnail types that will automatically
use Screenshot if there is no camera and 3dview, or workbench render
with shading settings from the largest 3dview.

Cleanup: Pass const mesh argument

Also remove unnecessary parantheses.

Cleanup: Move mesh_convert.c to C++

This should allow easier changes when it's helpful to use C++ types.
The diff is for a test on the buildbot.

Geometry Nodes: Transfer attributes in the curve to mesh node

This patch allows point and spline attributes to be transferred to the
mesh generated by the curve to mesh node. All dynamic named and
anonymous attributes are transferred. So a user-created attribute will
be transferred, but "radius", "tilt" or the handle position attributes
won't be transferred by default and will need to be copied first.
This trade-off is made for performance, since most of the time, users
won't need these attributes copied.

Generally, attributes are transferred to the point/vertex domain.
However, if they have the same name as a built-in mesh attribute that
only exists on a different domain, like "shade_smooth", then they can
be transferred directly to that domain as well. Conversion directly to
the face corner domain is not necessary because there are no builtin
face corner attributes. I see this conversion directly to other domains
as an optimization we could use behind the scenes in the future as well,
when named attributes are less common.

For performance, I haven't tested which of the following is better:
```
for each spline combination:
for each attribute:

for each attribute:
for each spline combination:
```
For now I used the existing loop to avoid more threading overhead.

Cycles X: set integrator state size relative to the number of GPU cores

More specifically, 16x the max number of threads on all multiprocessors,
with 1048576 minimum.

What this effectively does is double the state size on the very high end
GPUs like RTX A6000 and RTX 3080 while leaving the size unchanged for
others. On the RTX A6000 I there are 2-10% render time reductions on our
benchmark scenes. The biggest reduction is on the barbershop interior, as
scenes with more objects and shaders are more likely to benefit from
improved coherence.

This also adds an environment variable for developers to test different
sizes, and debug logging about the size and memory usage.

Geometry Nodes: Simplify using OutputAttribute in a vector

Store the optional temporary span storage as a unique_ptr and move
it in the move constructor, to avoid the need to add a special move
constructor that clears the "show_warning" fields from it. Maybe this
is very slightly slower, but we'll need this class less often in the future
anyway.

Cleanup: Add built-in check for an attribute ID

Rename App Menu to Blender Menu

"App" is a name reserved for the application templates at the moment.
It may become its own term in the near future if Templates are separated
from "Apps".

So since this is a name not exposed to the users we should renamed it
sooner than later.

Note that this will require scripts to update since the name of the
class is renamed here.

This also requires an update in the User Manual.
