purge: move extension into core mercurial

The motivation is simple: it's nicer to avoid gating basic
functionality.

To reduce the risk of people shooting themselves in the feet, `--confirm` is now
the default, unless the extensions is loaded..

For review of the body of the purge command, use this instead of what
hg/phabricator will show (the block of code is modified, not just
moved):
