the previous implementation used set_string_truncated. This is not only
awkward with this kind of "streaming" string (and therefore lead to an
inefficient and incorrect initial implementation) but that function also
truncates strings of width 1 when there is only a single char available.
The implementation here is performant, correct and also handles the
single width case correctly.
If the terminal doesn't send the primary device attributes response to
the query, the `terminal::supports_keyboard_enhancement` function from
crossterm may timeout and return an Err.
We should interpret this error to mean that the terminal doesn't support
the keyboard enhancement protocol rather than an error in claiming the
terminal.

* deps: Resolve bitflags 2.0 breaking changes
Bitflags 2.0 release made some breaking changes requiring some small
changes to the Helix codebase.
Almost all of the necessary changes are to manually `#[derive(..)]`
trait implementations which are no longer automatically derived for
all bitflags. All of these were previously automatically derived:
#[derive(PartialEq, Eq, PartialOrd, Ord, Hash, Debug, Clone, Copy]
I have derived the minimum traits for each bitflag type.
The other change was to the `.bits` field. This is now a `.bits()`
method so the usage of this has been updated in the `Borders` type.

In my testing this takes around 3-4ms in terminals that support the
enhanced keyboard protocol (Kitty, WezTerm) and a few hundred
microseconds in terminals that don't (st, Alacritty).
Wether the host terminal supports keyboard enhancement can be cached
for the lifetime of a Helix session.
Caching this lookup prevents a potential lockup within crossterm's
event reading system where the query for the keyboard enhancement
support waits on the next keyboard event, which can happen if the
crossterm event stream is checked by `tokio::select!` in another
thread.
This moves the `Application::claim_term` and
`helix-term::application::restore_term` functions into the helix-tui
crate. How the terminal should be claimed and restored is a TUI concern
and is implemented differently through different TUI backends.
This cleans out a lot of crossterm and TUI code in Application and
makes it easier to modify claim/restore based on information we query
from the terminal host. The child commit will take advantage of this
to cache the check for whether the host terminal supports the keyboard
enhancement protocol. Without this change, caching that information
takes much more code which is not easily reusable for anything else.
The code to restore the terminal is somewhat duplicated by this patch:
we want to restore the terminal in cases of panics. Panic handler hooks
must live for `'static` and the Application's terminal does not.
Underline styles are mutally exclusive and overwrite each other.
Therefore implementing as an modifier lead to incorrect behaviour
when the underline style is overwritten.
For backwards compatability the "underline" modified is retained (but
deprecated). Instead the "underline_style" and "underline_color"
optios should be used to style underlines.
The cxterminfo crate has been used over popular alternatives
like `term` since it supports querying for extended capabilities
and also for it's small codebase size (which will make it easy
to inline it into helix in the future if required).
* Refactor menu::Item to accomodate external state
Will be useful for storing editor state when reused by pickers.
* Add some type aliases for readability
* Reuse menu::Item trait in picker
This opens the way for merging the menu and picker code in the
future, since a picker is essentially a menu + prompt. More
excitingly, this change will also allow aligning items in the
picker, which would be useful (for example) in the command palette
for aligning the descriptions to the left and the keybinds to
the right in two separate columns.
The item formatting of each picker has been kept as is, even though
there is room for improvement now that we can format the data into
columns, since that is better tackled in a separate PR.
