Cleanup: WM append code: de-duplicate post-make-local process a bit.

Cleanup: Rename USER_APP_LOCK_UI_LAYOUT

There will be other settings that lock other aspects of the
UI layout (e.g., resizing of editors). So better to name
this setting what it actually handles (the corners).

New name: USER_APP_LOCK_CORNER_SPLIT

Differential Revision: D12516

Rename show_layout_ui > show_corner_split and remove from UI

This breaks API compatibility. However we are now grouping this setting
in the proper section (preferences.apps), so scripts had to update anyways.

So they may as well do it for the final name.

The reason to remove from the UI is that this is intended for app setup,
and as such it should not be exposed to final users until we have apps
better presented (for 3.1 hopefully).

App Settings: Regions Visbility Toggle

The toggle that allow users to "show" the region (header, toolbar, ...)
when it is collapsed can now be configured for the apps.

Note: This option is not visibile in the UI.

App Settings: Edge Resize

This prevents both editor resize as well as regions (e.g., the toolbar).

Note: This option is not visible in the UI.

Hide empty keymap warnings when running a template

Assets: Recursive reading of asset libraries

With this, asset libraries can be directory structures and all assets in
sub-directories will show up in an Asset Browser.

With complex directory structures and many .blend files inside, asset
library reading will be quite slow for now. There's initial work being
done to introduce indexing for this (T82979), other optimizations are
being discussed as well.

Addresses T91406.

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.

Cleanup: Add built-in check for an attribute ID

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.

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.

UI: Remove Menus & Show Wait Cursor When Saving

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.

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.

UI: wait for input for operators that depend on cursor location

Support waiting for input so operators that depend on the
cursor location are usable from menus / buttons.

Use an operator type flag which the user interface code checks for,
waiting for input when run from a menu item.

This patch only supports this feature, there are no functional changes.

The motivation for this change is discoverability since some actions
were either hidden or broken when accessed from menus
(where the behavior of the operator depended on the menu location).

In general, waiting for input is *not* an efficient way to access tools,
however there are over 50 operators with a "wait_for_input" property
so this isn't introducing a new kind of interaction,
rather exposing this in a way that does not need to be hard-coded into
each operator, or having modal callbacks added for the sole purpose
of waiting for input.

Besides requiring boiler plate code using a "wait_for_input" property
has the added down-side of preventing key shortcuts from showing.
Only the menu items will enable the property,
causing them not to match key-map items.

UI: split screenshot area into a separate operator

While the screenshot operator showed an "Area" option,
