Valentin Gagarin 4781e7fa70 Document each store type on its own page
This makes for more useful manual table of contents, that displays the
information at a glance.

The `nix help-stores` command is kept as-is, even though it will show up
in the manual with the same information as these pages due to the way it
is written as a "`--help`-style" command. Deciding what to do with that
command is left for a later PR.

This change also lists all store types at the top of the respective overview page.
