Sorry for the delay - I've been meaning to look at this for a while. The change itself looks good and the behavior feels right. I just have one small nit

Resolves #5425. Design rationale detailed in #5425 comments.
I'm not entirely sure whether this change is desired, but am still submitting this optimistically as I think it makes a lot of sense. I use Helix on a touch screen device (phone) sometimes and find this extremely useful for selecting code blocks as touches are easier to do than key strokes on such devices. It annoys me that currently the only way to extend a selection would be to use a keyboard.
This PR should improve the mouse UX. It's now possible to extend the primary selection with mouse clicks. The original drag-to-yank behavior is also retained.
With this PR, the editor no longer collapses all selections into a single point on mouse clicks unconditionally. Instead, it extends the primary selection to the point click when it's in select mode (secondary selections are still discarded for consistency). Normal mode behavior is left untouched.
