bug#49005: 28.0.50; Not possible to jump to first or last completions entry in fido-vertical-mode

In the brand new fido-vertical mode, completions are not cycled in contrast to icomplete-vertical-mode.
There is not yet a function to jump to the first or last completions entry, which sometimes can be helpful.
This patch would proposes two simple helper functions for doing that.

Thank you!

bug#49005: 28.0.50; Not possible to jump to first or last completions entry in fido-vertical-mode

[João Távora]

No, no, makes a lot of sense.  I just haven't looked at your code
yet in depth.

Your implementation seems to repeat some logic, and I'd rather
reuse paging code, so maybe you can work on that: reducing code
duplication.  But as soon as I have time I'll look at this and offer some
suggestions.

Sorry for the delay, and keep bumping this if I forget.

João

I've pushed a solution to this in:

    commit 96bbd6f0a7f20ae77bcd8a477b54b11ba5b42cc6 (HEAD -> master, origin/master, origin/HEAD)
    Author: João Távora <joaotavora@gmail.com>
    Date:   Tue Aug 17 12:48:37 2021 +0100
     
        Jump to first,last completion with M-<, M-> in icomplete-vertical-mode
     
        Fixes: bug#49005
     
        Co-authored-by: Simon Lang <simon.lang@outlook.com>

With the aforementioned de-duplications and binding it to M-< and M->
so that it also works easily for tty emacsen.  Let me know what you
think.

Thanks,
João
