32396: _git: fix __git_committish_range_{first,last} and __git_is_committish_range
- Ranges with 3 dots would always fail, because the non-greedy
  expansion  %..(.|)* in __git_committish_range_first would only
  remove '..' and never three dots. 'a...b' would end up in 'a.'.
  Use ${${1%..*}%.} instead.
- Use a similar approach for __git_committish_range_last.
- Wrap them in another expansion to replace empty results with 'HEAD'.
  Git man-page states omitted range ending are being replaced with
  HEAD. This rule has to be followed to make completions like
  'git log foo.. -- <tab>' work properly.
- Add an additional check to make sure none of the extracted first/last
  parts contain additional '..' in invalied ranges such as 'a..b..c'.
  This gets rid of the 'TODO:' and ideally saves a few unneded
  calls to git rev-parse.
