* 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.
