`print_ui_layout_tree` is exported, but not usable

What you did

Search for "debug" in docs, and find this tempting function: https://docs.rs/bevy/latest/bevy/ui/debug/index.html and try to use it.

What went wrong

It's impossible to use outside of the engine, because UiSurface is not exported.

bevy/crates/bevy_ui/src/layout/mod.rs

Lines 27 to 28 in 82f6f70

	pub mod debug;
	pub(crate) mod ui_surface;

Additional information

It's not clear to me if

• This is intended to be user-facing and UiSurface should be exported
• print_ui_layout_tree should not be exported

IMO we should make this user-facing. @nicoburns will have a more informed opinion here though.
