vim-patch:9.0.1753: can't move to last non-blank char

Problem: can't move to last non-blank char
Solution: Make g<end> behave like that

Make it possible to move to last non-blank char on a line

We can distinguish between g0 and g^ to move to the very first character
and the first non-blank char.

And while we can move to the last screen char, we cannot go to the last
non-blank screen char.

Since I think g$ is the more widely used and known movement command (and
g<end> is synonymous to it) change the behaviour of g<end> to move to
last non-screen char instead and don't have this be the same command as
the g$ command anymore.

If you want to keep the old behaviour, you can use:

```
nnoremap g<end> g$
```

Add a test to verify the behaviour.
