Send selection to editor.select on android

Bug

What's the new behavior?

Selections are sent to the editor.select command instead of ranges

How does this change work?

Instead of sending ranges, we take the existing selection from the editor and apply the range's anchor and focus.

Have you checked that...?

• The new code matches the existing patterns and styles.
• The tests pass with yarn test.
• The linter passes with yarn lint. (Fix errors with yarn prettier.)
• The relevant examples still work. (Run examples with yarn watch.)

Does this fix any issues or need any specific reviewers?

These changes are mostly from #3023. These should disappear when merging it.

I saw there is also onDrop that send a range into the editor.select command. Is the API allows this? If simple ranges are permitted in editor.select, then I'll simply close the pull request.

It also seem that partial object are usually allowed in commands. With #2495 a range is simply a partial selection.

If we want to move away from partial object, I can widen this pull request. But that's really up to you.

Ranges can be sent to editor.select and are handled correctly. I will close this for now.
