log: add --clear-decorations option

Browse source 
The previous changes introduced a new default ref filter for decorations
in the 'git log' command. This can be overridden using
--decorate-refs=HEAD and --decorate-refs=refs/, but that is cumbersome
for users.

Instead, add a --clear-decorations option that resets all previous
filters to a blank filter that accepts all refs.

used as decoration if they match `HEAD`, `refs/heads/`, `refs/remotes/`,
`refs/stash/`, or `refs/tags/`.
--clear-decorations::
When specified, this option clears all previous `--decorate-refs`
or `--decorate-refs-exclude` options and relaxes the default
decoration filter to include all references.
