This commit annotates fonts with a boolean that indicates whether
we think it contains glyphs with emoji presentation, and then
passes the cluster.presentation field down to the shaper.
If the presentation doesn't match the current font in the fallback,
then it will be skipped until we exhaust its options.
`wezterm ls-fonts` also shows whether we think a font has emoji
presentation.

* docs/term: add information to make it work with WSL
* Adapt recent changes that automatically set WSLENV, add info on how to install terminfo with nixpkgs
* Apply suggestions from code review

Test scenario is:
* Create a split
* in each pane run: `printf "\e[?1004h" ; od -c`
* Focus the panes, focus another window, and focus the window again
* The I and O events appear in the panes when changing their focus.
* Previously, only the active pane would get focus events when the
window focus changed.

The man page states:
> For each parameter, the first obtained value will be used.
but then later says:
> It is possible to have multiple identity files specified in
> configuration files; all these identities will be tried in sequence.
> Multiple IdentityFile directives will add to the list of identities
> tried (this behaviour differs from that of other configuration
> directives).
So that's what this commit does
The main culprit was the calloop feature that is used by default
in the underlying SCTK crate.
This commit:
* Routes keyboard processing via the same keyboard mapping code
that we use for X11
* Implements key repeats directly, and with awareness of elapsed
time in case the repeat rate is quicker than the event dispatching
quantum
* Disables the calloop feature of SCTK and let us do our own polling
of the wayland connection.
Critically, key repeat is sticky and unpredictable while calloop is
enabled.
