53c47143fd term: scope the conpty resize quirks better to conpty on windows
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.

75e785e01e allow using CSS style color specs in the config
This change also allows removing the dep on the palette crate,
which I found to be difficult to use (API changed often, and relied
on a lot of `.into` that was hard to follow and reconcile across
upgrades).  We already pulled in the csscolorparse crate as an indirect
dep of colorgrad, so we can replace the color conversion we need for
sixel with that crate while we're in here.

f89f2b5248 term: reset to single width line when clearing a line
Previously overlooked because we didn't render or otherwise
change behavior: after running vttest and running ls, some
lines still had double width/height set.

8cb74c62d2 allow setting selection colors with alpha values
This commit allows the following configuration:

```
wezterm -n --config 'colors = { selection_fg = "clear", selection_bg = "rgba:50% 50% 50% 50%" }'
```

which sets the selection_bg to fully transparent, and selection_bg to
50% transparent gray.

When selection_fg is fully transparent we'll use the normal fg color.

When selection_bg is partially (or fully!) transparent, it will be
alpha blended over the current cell background color.

To support this, the config file will now accept rgba colors specified
as 4 whitespace delimited numeric values. If a value ends with `%` it
is interpreted as a number in the range 0-100.  Otherwise, it is
interpreted as a number in the range 0-255.  The 4 values are
red, green, blue, alpha.

At this time, only the selection_fg and selection_bg settings accept
alpha values.

98f35bbf24 bidi: tag Line with bidi mode
This commit refines bidi property handling:

* experimental_bidi has been split into two new configuration settings;
  `bidi_enabled` (which controls whether the terminal performs implicit
  bidi processing) and `bidi_direction` which specifies the base
  direction and whether auto detection is enabled.
* The `Line` type can now store those bidi properties (they are actually
  split across 3 bits representing enabled, auto-detection and
  direction)
* The terminal now has a concept of active bidi properties and default
  bidi properties
* The default properties are pulled from the wezterm configuration
* active bidi properties are potentially set via escape sequences,
  BDSM (which sets bidi_enabled) and SCP (which sets bidi_direction).
  We don't support the 2501 temporary dec private mode suggested by
  the BIDI recommendation doc at this time.
* When creating new `Line`'s or clearing from the start of a `Line`, the
  effective bidi properties are computed (from the active props,
  falling back to default propr) and applied to the `Line`.
* When rendering the line, we now look at its bidi properties instead
  of just the global config.

The default bidi properties are `bidi_enabled: false` and
`bidi_direction: LeftToRight` which corresponds to the typical
bidi-unaware mode of most terminals.

It is possible to live reload the config to change the effective
defaults, but note that they apply, by design, to new lines being
processed through the terminal.  That means existing output is
left unaffected by a config reload, but subsequently printed lines
will respect it.  Pressing CTRL-L or otherwise contriving to have
the running application refresh its display should cause the
refreshed display to update and apply the new bidi mode.

8ee6739ece config: expand canonicalize_pasted_newlines
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`.

e188406dfc make semantic zones more cacheable
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.

1fd53d4a5d mux: propagate User Vars across to the client
user vars were stubbed out.  This commit adds storage for them
in the mux client and adds a new notification that publishes each
var as it is changed.  That differential stream is applied to the
storage in the mux client when it is received.

```lua
local wezterm = require 'wezterm'

wezterm.on("update-right-status", function(window, pane)
  local woot = pane:get_user_vars().woot
  window:set_right_status(tostring(woot))
end);

return {
  unix_domains = {
    {name="unix"},
  },
}
```

then running:

* `wezterm connect unix`
* in that session: `printf "\033]1337;SetUserVar=%s=%s\007" woot `echo -n nice | base64``

causes `nice` to show in the status area.

4524abcdba gui: revise win32-input-mode flow
We need 100% of the info for it to work correctly, so this commit:

* Exposes the keyboard encoding mode via the Pane trait
* Adds the scan code to the RawKeyEvent
* Has the GUI perform the encoding if the keyboard is set that way
* Removes the basic encoder from termwiz in favor of the gui level one

The net result is that we bypass the Pane::key_up/Pane::key_down methods
in almost all cases when the encoding mode is set to win32-input-mode.

There is now a config option: allow_win32_input_mode that can be
used to prevent using this mode.

ce23ee9eb8 input: generate win32-input-mode for a subset of keys
This commit causes the terminal to emit win32-input-mode encoded key up
and down events for a limited subset of keys When win32-input-mode is
enabled.

We limit them to keys where we know the VK key code equivalent,
and where those keys are either not representable (eg: modifier
only key events), or may generate ambiguous output (eg: CTRL-SPACE
in different keyboard layouts).

However, in my experiments, modifier only key presses confuse powershell
and cause it to emit `@`, so I've disabled that in the code for now.

88b8cb3e21 term: fix overinvalidation of selection on Windows
Not 100% sure why this only really manifested on Windows, but
the symptoms were:

* Run powershell in a tab
* Run `dir`
* Hit enter a couple of times to show a couple of prompts
* Try using the mouse to select across the prompt boundaries

The selection would get invalidated crossing the boundaries.
I traced this down to the lines around those regions having
SEQ_ZERO as their sequence, so this commit ensures that lines
that are created as part of scrolling the screen are correctly
tagged with the current seqno from the terminal display.

Why only windows? Not totally sure; perhaps it is related to
something funky happening in the conpty layer and sending us
unusual escapes (eg: scroll margins?)
