ui: add ui.formatted configuration variable and accessor function.
This new configuration variable is similar in nature `ui.interactive',
but applying to output instead of input. This allows as to support
non-interactive sessions where formatted should be enabled, such as
when using the pager extension.
The variable itself is left undocumented; it is not intended for use
outside Mercurial and its extensions.
