This setting now allows specifying what the canonical format is;
previously it was a boolean that meant "don't change anything"
if false, and rewrite to CRLF if true.
It's now an enum with None, CR, LF, and CRLF variants that express
more control.
The config accepts true (maps to CRLF) and false (maps to None)
for backwards compatibility.
The default behavior is unchanged by this commit, however, I did
uncover a bug in the canonicalizer for inputs like `\r\r\n`.

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.
