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
* Run the codegen to update nerdfonts_data.rs:
`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
* Run the embedded vim command that will regenerate the table

Root cause is that font-config will try to find a single font that
satisfies a query like `fc-list ':charset=2686 3065'`, but if that
is impossible, there are no results.
The resolution is to split the query up and look for each individual
codepoint.

Previously we'd use the scaled-by-line-height-and-cell-width dimensions
for the text cursor, leading to oddly dimensioned block cursors when
`line_height` or `cell_width` were configured.
This commit captures the native cell dimensions into the RenderMetrics
which makes it feasible for the glyph and sprite rendering logic to
reason about it.
The cursor rendering now renders at the native size and position by
using a transform to scale and translate into the correct spot.
We could potentially use the same technique for eg: braille or
other non-drawing characters
(https://github.com/wez/wezterm/issues/1957) although that is more
complex than just this commit.

Previously we'd return the Url string. Now we provide a Url
object that provides access to the various elements of the Url.
This will cause slightly breakage for folks that were treating
it as a string in their status event handlers, for example.
The docs have been updated to show how to run with both this
new Url object and also continue to run on older versions of
wezterm.
They now also show how to manually percent decode the url
for older versions of wezterm.

Move the shortcode aliases out from the various emoji category
pages and into a new shortcode page.
Add variations, such as skin tones, to the different emoji
