histedit: cache description line
Navigating the curses-based histedit interface can be pretty slow
because it redraws everything whenever you make a change.
This patch simply replaces `@property` by `@util.propertycache` on the
`histeditrule.desc()` function so it's not re-calculated every time
the screen needs to be re-rendered. I timed it on an example of 30
simple commits, where I moved the top commit down 25 steps and then up
25 steps after. Before this patch, that (the whole `hg histedit`
invocation) took 11.6 s of CPU and after this patch it took 0.8 s).

== New Features == * The amend extension supports the `--currentuser` argument. * The amend extension supports the `--close-branch` argument. * The amend extension supports the `--secret` argument. * The uncommit extension supports the `rewrite.update-timestamp` config option. == New Experimental Features == == Bug Fixes == == Backwards Compatibility Changes == * A shell that supports `$(command)`` syntax for command substitution is now required for running the test suite. The test runner normally uses `sh`, so if that is a shell that doesn't support `$(command)` syntax, you can override it by setting `$HGTEST_SHELL` or by passing it to `run-tests.py --shell <shell>`. * The (experimental) narrow extension's wire protocol changed. If you're using it, you'll need to make sure to upgrade server and client at the same time. == Internal API Changes ==
