templater: introduce {latesttag()} function to match a pattern (issue4184)

This allows the latest class of tag to be found, such as a release candidate or
final build, instead of just the absolute latest.

It doesn't appear that the existing keyword can be given an optional argument.
There is a keyword, function and filter for 'date', so it doesn't seem harmful
to introduce a new function with the same name as an existing keyword.  Most
functions are pretty Mercurial agnostic, but there is {revset()} as precedent.

Even though templatekw.getlatesttags() returns a single tuple, one entry of
which is a list, it is simplest to present this as a list of tags instead of a
single item, with each tag having a distance and change count attribute.  It is
also closer to how {latesttag} returns a list of tags, and how this function
works when not given a '%' operator.
