This allows individual call sites to be able to force an immediate
resolution of the process information.
This should help to address https://github.com/wez/wezterm/issues/4811
wherein the problem seems to be that the cwd used for a new spawn
is taken from a stale read.
Previously we'd return the Url string. Now we provide a Url
object that provides access to the various elements of the Url.
This will cause slightly breakage for folks that were treating
it as a string in their status event handlers, for example.
The docs have been updated to show how to run with both this
new Url object and also continue to run on older versions of
wezterm.
They now also show how to manually percent decode the url
for older versions of wezterm.

- Removes closures and function calls for types that implement default:
```rust
// Change
let _my_str = get_str().unwrap_or(String::new);
// To
let _my_str = get_str().unwrap_or_default();
```
- Uses the `.cloned()/.copied()` methods where possible
- Use function pointer instead of simple closure
May improve performace, as closures generate more code, and this might
unlock some inlining opportunities.
Threads through a GuiPosition from mux window creation to allow it to be
used when the corresponding gui window is created.
SpawnCommand now has an optional position field to use for that purpose.
```lua
wezterm.mux.spawn_window {
position = {
x = 10,
y = 300,
-- Optional origin to use for x and y.
-- Possible values:
-- * "ScreenCoordinateSystem" (this is the default)
-- * "MainScreen" (the primary or main screen)
-- * "ActiveScreen" (whichever screen hosts the active/focused window)
-- * {Named="HDMI-1"} - uses a screen by name. See wezterm.gui.screens()
-- origin = "ScreenCoordinateSystem"
},
}
```

This allows removing a bunch of unwrap/expect calls.
However, my primary motive was to replace the cases where we used
Mux::get() == None to indicate that we were not on the main thread.
A separate API has been added to test for that explicitly rather than
implicitly.
This is a step towards making it Send+Sync.
I'm a little cagey about this in the long term, as there are some mux
operations that may technically require multiple fields to be locked for
their duration: allowing free-threaded access may introduce some subtle
(or not so subtle!) interleaving conditions where the overall mux state
is not yet consistent.
I'm thinking of prune_dead_windows kicking in while the mux is in the
middle of being manipulated.
I did try an initial pass of just moving everything under one lock, but
there is already quite a lot of mixed read/write access to different
aspects of the mux.
We'll see what bubbles up later!
reconciling causes gui windows to be created and allows for stuff like
this, that would otherwise fail because the gui window hadn't been
created yet.
```lua
local wezterm = require 'wezterm'
local mux = wezterm.mux
wezterm.on("gui-startup", function()
local tab, pane, window = mux.spawn_window{}
window:gui_window():set_inner_size(1200, 1200)
end)
return {
}
```
Allow iterating all windows at the mux layer.
windows allow iterating tabs.
Tabs allow iterating panes.
Versions of iteration that report additional information (like index,
active and positioning) are also added.
Panes can now reference their containing tab and window objects.
Tabs can now reference their containing window object.

Previously, the mux layer had no internal understanding of titles other
than the Pane::get_title method to return state from a pane.
Users have asked for ways to explicitly set titles on windows and tabs,
so this commit is a step towards that.
The mux window and tab objects now store a title string.
The terminal layer now emits Alert::WindowTitleChanged when the window
title is changed via eg: OSC 0 or OSC 2.
The mux layer will respond to Alert::WindowTitleChanged by resolving the
window that corresponds to the source pane and amending its title.
The MuxWindow and MuxTab objects now provide accessor methods for the
title.
TabInformation (as used by format-tab-title and format-window-title) now
exposes the underlying window_id as well as tab_title and window_title.
The tab title can be changed via the lua MuxTab type, but there is not
currently an escape sequence associated with this.
The defaults for format-tab-title and format-window-title don't
currently consider these new title strings.

The intent is to expose Mux related functions to lua, so `wezterm.mux`
will be that module table.
In order to test this out in the debug overlay, I realized that the
overlay was running functions in a different thread and didn't have
access to the mux, so this commit also tweaks the debug overlay repl to
execute the input in the main thread.
The result is that it is now possible to do
`wezterm.mux.active_workspace()` in the debug overlay to print the
active workspace name.
More functions will follow.
