Previously, we'd create a clipboard handler associated with a GUI window
and take care to pass that down to the underlying Pane whenever we
spawned a new pane.
For the mux server, instead of being associated with a GUI window, the
clipboard was a special RemoteClipboard that would send a PDU through
to the client that spawned the window.
The bug here was that when that client went away, the clipboard for
that window was broken.
If the mux server was the built-in mux in a gui process this could
leave a tab without working OSC 52 clipboard support.
This commit restructures things so that the Mux is responsible for
assigning a clipboard handler that rephrases the clipboard event
as a MuxNotification.
Both the GUI frontend and the mux server dispatcher already listen
for mux notifications and translate those events into appropriate
operations on the system clipboard or Pdus to send to the client(s).

Previously, we'd just default the resize quirk on for all programs on
Windows.
That pessimizes the otherwise fine behavior of `wezterm ssh` or mux
connections to unixy platforms.
This commit moves the quirk out of the config trait and makes it
a runtime property of the terminal, and then arranges for it
to be set when we know that we set up a conpty for the terminal.

Pretty much the same test plan as b4c4c85683
but start wezterm:
./target/debug/wezterm -n --config 'ssh_domains={{name="s",remote_address="localhost"}}' connect s
This reliably propagates focus=true events, but if the client switches
focus away from a mux pane to a local pane, then the focus=false event
may not be propagated to the remote mux.

wezterm cli spawn, and wezterm cli split-pane can use this information
to pick a default for the pane id when invoked from outside of wezterm.

This commit centralizes the focus-loss logic to the Window so
that activating a new tab will deactivate the pane in the current
window.
Note that this cannot see overlays in the gui, but overlays shouldn't
care about focus, so it should be ok.

This commit enables the following config to work for local (not mux yet!)
panes:
```lua
local wezterm = require 'wezterm'
wezterm.on("format-tab-title", function(tab, tabs, panes, config, hover, max_width)
if tab.is_active then
return {
{Background={Color="blue"}},
{Text=" " .. tab.active_pane.title .. " "},
}
end
local has_unseen_output = false
for _, pane in ipairs(tab.panes) do
if pane.has_unseen_output then
has_unseen_output = true
break;
end
end
if has_unseen_output then
return {
{Background={Color="Orange"}},
{Text=" " .. tab.active_pane.title .. " "},
}
end
return tab.active_pane.title
end)
return {
}
```

This commit decomposes the main get_semantic_zones method into two
parts:
* A per-line portion, where the line ranges are cached (invalidated on
change)
* The overall screen portion, where the line ranges are merged
This changes the overall complexity of computing zones from
O(width * scrollback-height)
To an incremental:
O((width * number of changed lines since last query) + scrollback-height)
You can see some samples of elapsed time below; those show the times for
running both the old and the new implementation on the same data. The
number of lines/zones in the scrollback increases with each call and you
can see that the new implementation is a bit faster anyway at low
volumes but is significantly faster as the number of lines/zones
increases, because the amount of work is reduced.

Rather than just quitting the app and potentially silently killing off
a number of panes that might be running in other workspaces, we now
will pick one of those workspaces and activate it.
refs: #1531
This action causes the active workspace for the gui to change.
If the name is omitted a random name will be generated.
If the workspace doesn't exist, it will be be created.
The optional spawn parameter can be used to launch a specific
program into the new workspace; if omitted, the default prog
will be used.
The gui only supports a single active workspace. Switching workspaces
will repurpose existing gui windows and re-assign them to windows
in the new workspace, adjusting their size to fit those windows,
spawning new windows or closing unused windows as required.
The gui now exits when there are no panes in the active workspace,
rather than no panes at all.

This commit updates the last input time for the active client
id when calling into local pane. That time is visible in the
`wezterm cli list-clients` output.
The mux now has a notion of which client is actively doing things.
This allows, for example, newly spawned windows to take on the
active workspace for a given client.
The gui now assigns a client id on startup, and sets the active
workspace to `default`.
The mux server temporarily overrides the active id to that of
the currently dispatching client when processing PDUs.

Tidies up some code duplication within the mux protocol handler.
Move some of the logic into Mux, remove legacy Spawn Pdu to reduce
more duplication.
I want to dedup some of the similar logic that exists in the gui
spawn implementation as well in a follow up.
