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.
This is not exposed through any UX; the mux api allows setting
the workspace and propagating information about windows whose
workspace has changed.
Windows start with a blank workspace name.
This is just plumbing; nothing uses it yet.

Define a way to compute a client ID and pass that through to the
mux server when verifying version compatibility.
Once associated, the session handler will keep some metadata
updated in the mux.
A new cli subcommand exposes the info:
```
; ./target/debug/wezterm cli list-clients
USER HOST PID CONNECTED IDLE WORKSPACE
wez mba.localdomain 52979 30.009225s 1.009225s
```

This is slightly misusing or misattributing things, but in
the context of the problem at hand, it is OK.
The issue is that palette changes are normally signalled by
the terminal instance in response to escape sequences. Those
changes are propagated to the mux client through the existing
alerting channel.
If the palette is changed implicitly via a config change, then
the terminal doesn't trigger that alert and the mux client(s)
don't know that they need to refresh the palette.
This commit tracks the last config generation per pane and
synthesizes a palette alert when it changes.
It might be better to have another variant of alert to indicate
config changes.

This doesn't make a huge difference; I think we already addressed
the worst of the overhead with a combination of
eae327efcc
and the more recent commits to avoid over invalidation around
cursor movement and screen scrolling.
The numbers I see are a very small number of bytes per second when
scrolling through eg: vim and aren't crazy or alarming.
So I'm going to consider the related issue resolved!

Rather than using the configured initial window size, use the
size of the current tab to size the newly spawned tab.

Terminal now maintains a sequence number that increments
for each Action that is applied to it.
Changes to lines are tagged with the current sequence number.
This makes it a bit easier to reason about when an individual
line has changed relative to some point in "time"; the consumer
of the terminal can sample the current sequence number and then
can later determine which lines have changed since that point
in time.

This commit causes a window-config-reloaded event to trigger
when the appearance (dark/light mode) is changed on macos.
It also arranges to propagate the window level config to newly
spawned panes and tabs, created both via the gui and via the
CLI/mux interface.

in the same vein as d657721163
this commit introduces more assertive signalling from the remote
mux when a pane is closed so that the client can update.
