This continues #8202 by fixing two of the known issues: `goto_split` key
binds work and closing a split moves focus to the proper place.
A big improvement in this PR is that for the first time ever in our GTK
backend, the up/down/left/right `goto_split` bindings **use spatial
navigation.** "Spatial navigation" means that the direction to move
focus is done based on the nearest split _visually_ from the current
split, rather than via a tree traversal. We did this on macOS a couple
months ago, with a lot more details there: #7523
Similar to macOS, the spatial navigation is currently based on top-left
corner. Now that our split tree is implemented in Zig though it should
be a lot easier for us to work in the current cursor position as the
reference point.
~~🚧 TODO: Going to add some unit tests for the spatial navigation before
merge.~~
This avoids jitter when resizing splits. I didn't see any jitter before
splits but conceptually its possible. The issue is that since we're
updating the overlay DURING A RESIZE, changing the dimensions of any
part of the widget tree causes GTK warnings and a bunch of laggy
updates.
Instead, we copy the label text to a property and update it on the idle
callback along with everything else. This also provides a natural
debounce to the label.
This also fixes a bug where we were setting custom cursors on the wrong
gtk widget, this showed up most terribly with `mouse-hide-while-typing`
where the mouse would never reappear.

This PR adds a "tabs" title bar style similar to the macOS title bar
style. When `gtk-titlebar-style=tabs` the title bar and the tab bar
will be merged together.
The config entry for controlling this is kept separate from macOS as
macOS has more styles defined that don't map to a GTK title bar style
and it's likely that users that use both macOS and GTK would want
different settings for each platform.
We only need properties for things that are bound via the blueprint
files. Otherwise, its kind of just a pain. This fixes a bug where it
wasn't being properly set initially anyways because we didn't trigger
syncAppearance.
