28cef56ad2 Geometry Nodes: support capturing multiple attributes at once
By capturing multiple attributes with one node, the user can make sure that those
are evaluated together in the same context. This can be quite a bit more efficient
compared to capturing multiple fields separately (also because we don't optimize
grouping multiple capture nodes together yet).

The change is fully backward compatible. Forward compatibility has been added
for some cases. Especially, files created in older versions that are saved with this
newer version will still work in the older version.

f920d05820 Cleanup: don't require socket items to store socket type
This change helps when the socket type is not stored explicitly,
but is e.g. derived from a custom data type like `CD_PROP_FLOAT`.

96db947f16 Geometry Nodes: show info in simulation node when it is baked
This adds the same overlay that already exists for the bake node to the simulation output node.
Without this, it's quite hard to see if the simulation zone is baked or not currently.

176c6ef329 Geometry Nodes: unify menu switch with other nodes with dynamic sockets
This changes the menu switch socket to use the socket-items system
(`NOD_socket_items.hh`) that is already used by the simulation zone, repeat
zone, bake node and index switch node. By using this system, the per-node
boilerplate can be removed significantly. This is especially important as we
plan to have dynamic socket amounts in more nodes in the future.

There are some user visible changes which make the node more consistent with
others:
* Move the menu items list into the properties panel as in 0c585a1b8a.
* Add an extend socket.
* Duplicating a menu item keeps the name of the old one.

There is also a (backward compatible) change in the Python API: It's now
possible to directly access `node.enum_items` and `node.active_index` instead of
having to use `node.enum_definition.enum_items`. This is consistent with the
other nodes. For backward compatibility, `node.enum_definition` still exists,
but simply returns the node itself.

Many API functions from `NodeEnumDefinition` like
`NodeEnumDefinition::remove_item` have been removed. Those are not used anymore
and are unnecessary boilerplate. If ever necessary, they can be implemented back
in terms of the socket-items system.

The socket-items system had to be extended a little bit to support the case for
the menu switch node where each socket item has a name but no type. Previously,
there was the case without name and type in the index switch node, and the case
with both in the bake node and zones. The system was trivial to extend to this
case.

5f3ad33f38 Geometry Nodes: decentralize headers for some nodes
`NOD_zone_socket_items.hh` contained code for different nodes. It's better to
split this into headers per node, because that scales better. Also it helps to
keep the code for each individual node more closely together.
