Also move the component module in the item_Tree module
register_component -> register_item_tree
ComponentItemTree -> ItemTreeNodeArray
For #3323
Rationale from that issue:
Right now, we use the term `component` in the Slint language and in the compiler to be a a tree of elements that can be used as an element in a .slint file.
The term is also currently used in the runtime as a tree of runtime Items that are allocated together. (declared in ComponentVTable)
But there are no 1 to 1 mapping between a `component` in the slint language, and a runtime Component.
(for example, the items behind a `if` or `for` or `PopupMenu` are in a different runtime component. And `component` declared in Slint are often inlined)
So we should rename the internal runtime `Component` to `ItemTree`
The currently public `slint::ComponentHandle` wraps the "root" of the ItemTree, but that's ok because it is generated from a .slint `component`, so it doesn't change name
Make text_input_byte_offset_for_position and text_input_cursor_rect_for_byte_offset
low-level in the API, where the implementation becomes easier. Two
helper functions in TextInput in turn collect the necessary parameters
and thus also reduce the amount of duplicated code.
This also decouples the renderer further from the window.
The default impl of unregister_component in WindowAdapterSealed would call free_graphics_resources
on the rendere. Any re-implementation would have to do the same,
which the winit backend forwarded through
the winit backend specific internal renderer interface.
Instead, the original call site for unregister_component now calls
free_graphics_resources and unregister_component (for accessibility tree dirty notification).
Replace register_root_component in the WindowAdapterSealed altogether with
a default font size getter on the renderer.
This is overall simpler and allows removing the doc-hidden getter in the software renderer.
