tags: write a separate tags cache file for unfiltered repos

Since we changed the format of the tags cache, we should bump the
filename. Before this patch, "tags" was being used for unfiltered
repositories. Change the naming scheme to be consistent and ensure
that a new cache file is used.

While I was here, I updated the docs to describe the existence of
multiple caches. I also added explicit test coverage for the creation of
the unfiltered tags cache.

Just exercise debugindexdot
Create a short file history including a merge.
  $ hg init t
  $ cd t
  $ echo a > a
  $ hg ci -qAm t1 -d '0 0'
  $ echo a >> a
  $ hg ci -m t2 -d '1 0'
  $ hg up -qC 0
  $ echo b >> a
  $ hg ci -m t3 -d '2 0'
  created new head
  $ HGMERGE=true hg merge -q
  $ hg ci -m merge -d '3 0'

  $ hg debugindexdot .hg/store/data/a.i
  digraph G {
  	-1 -> 0
  	0 -> 1
  	0 -> 2
  	2 -> 3
  	1 -> 3
  }
