* Use Rectangle for breadcrumbs background.
* Use Rectangle for status bar bg.
* Use Rectangle for dropdown bg.
* Dirty global_element_depth_order invalidates sublayers
* Setting new parent may invalidate depth order
* Support per-instance pointer_events_enabled
* Remove workaround for #6241
Simplified layout algorithm by removing `content_origin`, and instead treating `(0.0, 0.0)` as origin point in every layout object. This change allows overflowing containers that are within auto-layout. The parent element will no longer be moved within the grid cell when its children overflow it.

# Important Notes
When implementing this change, I have found that when object's size was modified without ever touching its position, that change was not being picked up in the "modified children" list, and `on_updated` was never triggered. Because some sprites now are bottom-left aligned, that is now a common case and was reproducible on the auto-layout example scene. I ended up fixing it by introducing another dirty flag for `computed_size` changes. Right now that flag is applied very broadly (on each layout update), but in the future we might make it more precise by actually checking if the size was changed in the process.
I believe that this might also be a fix for #5095, as I cannot reproduce it anymore with those changes.
Implements #5640 and #5650
It made sense for me to implement those two together, as I wanted to make sure that the necessary widget API changes will support custom entry values for both dynamic and static data.
- Added support for custom dropdown labels defined on the method annotations
- Added shortening of static dropdown values, which resolves
| dynamic dropdown - custom labels | static dropdown - automatic shortening |

# Important Notes
During implementation I had multiple data update order issues caused by FRP network forming a diamond shape. Two inputs that are often updated together were combined with `all` combinator, and that was further fed into the dropdown. This caused two updates to propagate through the whole network, and one of them was immediately outdated. To fix this and similar future scenarios, I've added an `next_tick` FRP node. It buffers the incoming events until the next browser microtask, preserving only the last received event. Currently if it is called inside a `requestAnimationFrame` callback, the effects of that processing will only be rendered in the next frame. Later this can be mitigated by delaying the rendering logic until the microtask queue is empty.
Added support for named arguments in IDE.

Named arguments are now recognized in node expressions. The function argument placeholders are rendered around series of named arguments. Insertion and deletion of arguments either by connection dragging or by widget selection will cause arguments around to be rewritten into appropriate form, such that the meaning of the expression doesn't change. We no longer need to introduce any wildcards (`_`) in argument positions when editing an argument list of a resolved method.

For unresolved function calls, the old behaviour remains, as we don't have data about argument names or their desired order.

Added a dropdown widget to graph node for all span tree nodes that have tag values present. When an option is selected, the controller receives a partial expression update, which targets specific crumbs of the expression (similar to how edge endpoint updates work).

# Important Notes
Right now the dropdown widget is recreated every time the node is edited, including a dropdown option being selected. This causes it to close every time. I wanted to get around that by diffing span trees, but I wasn't able to do it in useful way. Additionally, current implementation of node input expression view heavily relies on being reinitialized from scratch every time. This led to more necessary changes than I was comfortable with for this task. I believe it will be easier to implement it as part of more complete widget support, especially after dynamic data support, as we will have proper widget type information.

Dropdown component. Planned to be used in nodes as a single and multiple selection widget, both for static and dynamically loaded values. Initial support is focused on static data, with limited support for dynamic sources. Notably, loading states are not supported yet. Full support for that is planned to be added later with widget lazy-loading.
- Supports single and multiple selections.
- Dedicated API for providing a static list of all entries.
- Range-based query API for dynamically loading data as it is scrolled (only basic support - will need more work for proper async lazy-loading).
- Internal entry cache and query batching to avoid querying data one by one (the batching for now is very basic, will have to be improved for proper lazy-loading).
- Automatic dropdown width adjustment based on the entry label lengths, up to a set max allowed value.
- Open and close animation.
- Keyboard support for focusing and selecting entries.

# Important Notes
Implementing the dropdown on top of grid-view have uncovered some assumptions around grid-view layers. It was assumed to always be a part of the component browser. Removing that assumption required a mechanism for propagating camera update information through layer tree. This is now implemented using a `camera_parent` layer field. Ideally each layer should simply have at most a single parent, and camera inheritance would follow that. That refactor turned out to be quite involved, so right now the simpler temporary solution is introduced in order to not delay this PR further.
