This causes `tmux -CC attach` to enter control mode and patch
into the terminal, printing out parsed event messages.

Adds some supporting methods for computing the `SemanticZone`s
in the display and a key assignment that allows scrolling the
viewport to jump to the next/prev Prompt zone.
This commit moves a bunch of stuff around such that `wezterm` is now a
lighter-weight executable that knows how to spawn the gui, talk to
the mux or emit some escape sequences for imgcat.
The gui portion has been moved into `wezterm-gui`, a separate executable
that doesn't know about the CLI or imgcat functionality.
Importantly, `wezterm.exe` is no longer a window subsystem executable
on windows, which makes interactions such as `wezterm -h` feel more
natural when spawned from `cmd`, and should allow
`type foo.png | wezterm imgcat` to work as expected.
That said, I've only tested this on linux so far, and there's a good
chance that something mac or windows specific is broken by this
change and will need fixing up.

025732d00f introduced deferred
window creation; the creation would get scheduled into the
spawn queue and then get run again a few milliseconds later
on the main thread.
For reasons that I don't understand, returning to the scheduler
loop to flush or otherwise process messages causes a wayland
protocol error.
Adjusting the notify routine to dispatch immediately if we're
already on the mux thread seems to resolve this.
While looking at this, I cleaned up a destruction order issue
with the opengl state that was then causing a segfault on shutdown.
I also removed a bit of dead paint related code that doesn't
appear to be needed any more.

This commit adds very basic first passes at representing the Pane
and GuiWindow types in lua script.
The `open-uri` event from 9397f2a2db
has been redefined to receive `(window, pane, uri)` parameters
instead of its prior very basic `uri` parameter.
A new key assignment `wezterm.action{EmitEvent="event-name"}` is
now available that allows a key binding assignment to emit an arbitrary
event, which in turn allows for triggering an arbitrary lua callback
in response to a key or mouse click.
`EmitEvent` passes the `(window, pane)` from the triggering window and
pane as parameters.
Here's a brief example:
```lua
local wezterm = require 'wezterm';
wezterm.on("my-thingy", function(window, pane)
local dims = pane:get_dimensions();
wezterm.log_error("did my thingy with window " .. window:window_id() ..
" pane " .. pane:pane_id() .. " " .. dims.cols .. "x" .. dims.viewport_rows);
window:perform_action("IncreaseFontSize", pane);
end)
return {
keys = {
{key="E", mods="CTRL", action=wezterm.action{EmitEvent="my-thingy"}},
}
}
```

Rather than having each call site add a window to the mux and then
call the front end to spawn a window, make the mux emit a signal
advising of a window spawn, and have the front end subscribe to
that signal.
