Using 'ref-filter' APIs implement the '--merged' and '--no-merged'
options into 'tag.c'. The '--merged' option lets the user to only
list tags merged into the named commit. The '--no-merged' option
lets the user to only list tags not merged into the named commit.
If no object is provided it assumes HEAD as the object.
Add documentation and tests for the same.
