topic: internal config option to fix hg pick behavior (issue6406)

After some consideration, hg pick was made to always use current topic (and
topic namespace), even if it's not set, in which case the resulting changeset
will not have any topic.

Previously the intended behavior was to only update topic if there was an
active topic, and not touch commit extras at all otherwise. That wasn't ideal,
since pick doesn't change active topic, and amending the just-picked commit
would unset its topic without clear user's intent to do so and to their
surprise.

Testing `hg fixup` command
==========================

  $ . $TESTDIR/testlib/common.sh

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > rebase =
  > evolve =
  > [diff]
  > git = 1
  > EOF

  $ hg help fixup
  hg fixup [OPTION]... [-r] REV
  
  aliases: fix-up
  
  add working directory changes to an arbitrary revision
  
      A new changeset will be created, superseding the one specified. The new
      changeset will combine working directory changes with the changes in the
      target revision.
  
      This operation requires the working directory changes to be relocated onto
      the target revision, which might result in merge conflicts.
  
      If fixup is interrupted to manually resolve a conflict, it can be
      continued with --continue/-c, or aborted with --abort.
  
      Note that this command is fairly new and its behavior is still
      experimental. For example, the working copy will be left on a temporary,
      obsolete commit containing the fixed-up changes after the operation. This
      might change in the future.
  
      Returns 0 on success, 1 if nothing changed.
  
  options:
  
   -r --rev REV  revision to amend
   -c --continue continue an interrupted fixup
      --abort    abort an interrupted fixup
