vim: Add some forced motion support (#27991)

Closes https://github.com/zed-industries/zed/issues/20971

Added `v` input to yank and delete to override default motion. The
global vim state tracking if the forced motion flag was passed handled
the same way that the count is. [The main chunk of code maps the motion
kind from the default to the overridden
kind](https://github.com/zed-industries/zed/pull/27991/files#diff-2dca6b7d1673c912d14e4edc74e415abbe3a4e6d6b37e0e2006d30828bf4bb9cR1249-R1254).
To handle the case of deleting a single character (dv0) at the start of
a row I had to modify the control flow
[here](https://github.com/zed-industries/zed/pull/27991/files#diff-2dca6b7d1673c912d14e4edc74e415abbe3a4e6d6b37e0e2006d30828bf4bb9cR1240-R1244).
Then to handle an exclusive delete till the end of the row (dv$) I
[saturated the endpoint with a left
bias](https://github.com/zed-industries/zed/pull/27991/files#diff-2dca6b7d1673c912d14e4edc74e415abbe3a4e6d6b37e0e2006d30828bf4bb9cR1281-R1286).

Test case: dv0
