Move to clearer reedline keyboard enhancement API (nushell#11045)

Go from the ill-defined `enable/disable` pairs to `.use_...` builders
This alleviates unclear properties when the underlying enhancements are
enabled. Now they are enabed when entering `Reedline::read_line` and
disabled when exiting that.

Furthermore allow setting `$env.config.use_kitty_protocol` to have an
effect when toggling during runtime. Previously it was only enabled when
receiving a value from `config.nu`. I kept the warning code there to not
pollute the log. We could move it into the REPL-loop if desired

Not sure if we should actively block the enabling of `bracketed_paste`
on Windows. Need to test what happens if it just doesn't do anything we
could remove the `cfg!` switch. At least for WSL2 Windows Terminal
already supports bracketed paste. `target_os = windows` is a bad
predictor for `conhost.exe`.

Depends on nushell/reedline#659
(pointing to personal fork)

Closes nushell#10982
Supersedes nushell#10998
