Windows, Mac, and Linux all have different behavior for how wordwraps are treated by keyboard shortcuts that jump to the beginning/end of a line. Previously, Flutter always stopped at wordwrapped lines. This PR aims to get the behavior correct on all platforms.

I believe I covered all of the cases affected by this PR in the tests, so to see exactly what the behavior should be on each platform, check the tests. These are the high level features:

  • When jumping to the start/end of a line multiple times, some platforms will jump between lines when it's a wordwrap and not a newline.
  • On Mac, home/end scroll to the start/end of the field without moving the cursor.
  • On Mac, shift + home/end selects to the start/end of the document.
  • Bugfix: Some of these kinds of shortcuts weren't calling bringIntoView, so they wouldn't cause the field to scroll.

Fixes #90993

I'm going to consider this blocked on #95948, which will bring back the extend/expand distinction needed to fix my last TODO (shift+home/end expands on Mac).

I think this was a typo in this test (probably by me in an earlier PR).

I think ideally this shouldn't be implemented in _LineBreak, as it's only supposed to tell you where the boundary is.

I've moved it to the action and I think it makes more sense there, thanks for the suggestion.

In order to do this I added continuesAtWrap to DirectionalCaretMovementIntent even though most of its subclasses don't use continuesAtWrap. Let me know if you think that's not alright.

(triage) @justinmc Looks like google testing got stuck on this one and I don't see a way to restart it.. Maybe push an empty commit?
