* Removed title update from main render loop
* Add to PaneFocused event
* term: only emit Alert::OutputSinceFocusLost for the first
seqno bump after losing focus, rather than on every bump.
That event indirectly causes the title to update

This used to make things such that the copy button for `console`
blocks would only copy the input and not the output, but it
doesn't seem to have that effect any more, and now just prevents
selecting portions of the output.
That's a PITA because eg: the CLI --help pages use `console`
to show which options are available.
I think something has probably changed somewhere in upstream mkdocs
because this used to work as I mentioned above.

test scenario is:
```
bash -c "sleep 5; for((i=0;i<30;i++)); do xdotool keydown --delay 0 Shift_L keydown --delay 0 9 keyup --delay 0 Shift_L keyup --delay 0 9; done"
```
That should cause a series of `(` characters to be emitted, but prior to
this commit is was usually mostly `9`'s.
What's changing here is:
* We copy the pertinent fields from the last xcb StateNotify event.
That ostensibly has the current modifier and layout state, but
because it comes from the X server, it doesn't factor in knowledge
from the IME.
* When processing an XCB key event, compute the current modifier
mask and override the XKB state with it.
* Now XKB will produce correct information about the key syms
* Restore the modifier state from the saved StateNotify information.

Procedure is:
* Download the `NerdFontsSymbolsOnly.zip` release asset
* Extract the font into assets/fonts

`cd termwiz/codgen ; cargo run`
* Apply formatting: `cd ../../ ; cargo +nightly fmt`
* Update the list of symbols in the docs:
* edit `docs/config/lua/wezterm/nerdfonts.md`
* delete the table
